+# How to contribute
+
+We definitely welcome your patches and contributions to gRPC!
+
+If you are new to github, please start by reading [Pull Request
+howto](https://help.github.com/articles/about-pull-requests/)
+
+## Legal requirements
+
+In order to protect both you and ourselves, you will need to sign the
+[Contributor License
+Agreement](https://identity.linuxfoundation.org/projects/cncf).
+
+## Code style
+
+We follow the [Effective
+Dart](https://www.dartlang.org/guides/language/effective-dart/style) code style.
+We rely on auto-formatting all whitespace -- this avoids having to discuss
+formatting during reviews. To format your code, run `dartfmt` from the root, or
+use the similar action in your [favorite Dart
+editor](https://www.dartlang.org/tools).
+
+All code must pass Dart analysis. If you are using an IDE or Dart-enabled editor
+it should raise analysis issues as you edit; alternatively validate from the
+Terminal:
+
+```
+dartanalyzer lib test
+```
+
+All analysis warnings and errors must be fixed; hints should be considered.
+
+## Running tests
+
+```
+pub get
+pub run test
+```
+
+## Guidelines for Pull Requests
+
+How to get your contributions merged smoothly and quickly.
+
+- Create **small PRs** that are narrowly focused on **addressing a single
+concern**.
+
+- For speculative changes, consider opening an issue and discussing it first.
+
+- Provide a good **PR description** as a record of **what** change is being made
+and **why** it was made. Link to a github issue if it exists.
+
+- Unless your PR is trivial, you should expect there will be review comments
+that you'll need to address before merging. We expect you to be reasonably
+responsive to those comments, otherwise the PR will be closed after 2-3 weeks of
+inactivity.
+
+- Keep your PR up to date with upstream/master (if there are merge conflicts, we
+can't really merge your change).
+
+- **All tests need to be passing** before your change can be merged. We
+recommend you **run tests locally** before creating your PR to catch breakages
+early on.
+
+- Exceptions to the rules can be made if there's a compelling reason for doing
+so.

+# Description
+The googleapis client demonstrates how to use Dart gRPC libraries to communicate
+with Google APIs.
+
+# Set up Google Cloud Platform project
+This example uses the Stackdriver Logging API. Please follow the documentation on
+[Stackdriver Logging Documentation](https://cloud.google.com/logging/docs/) to create
+a project and enable the logging API.
+
+Then follow the documentation to
+[create a service account](https://developers.google.com/identity/protocols/OAuth2ServiceAccount#creatinganaccount).
+This example uses the Logging/Logs Writer role.
+
+Create a new service key, download the JSON file for it, and save it as
+`logging-service-account.json`.
+
+# Run the sample code
+To run the example, assuming you are in the root of the googleapis folder, i.e.,
+.../example/googleapis/, first get the dependencies by running:
+
+```sh
+$ pub get
+```
+
+Then, to run the logging client sample:
+
+```sh
+$ pub run googleapis:logging
+```
+
+# Regenerate the stubs
+The Dart gRPC stubs and message classes are generated based on protobuf definition
+files from [googleapis/googleapis](https://github.com/googleapis/googleapis).
+
+To regenerate them, you will need to check out both
+[googleapis/googleapis](https://github.com/googleapis/googleapis) and
+[google/protobuf](https://github.com/google/protobuf).
+
+You will also need to have protoc version 3.0.0 or higher and the Dart protoc
+plugin version 0.7.9 or higher on your PATH.
+
+To install protoc, see the instructions on
+[the Protocol Buffers website](https://developers.google.com/protocol-buffers/).
+
+The easiest way to get the Dart protoc plugin is by running
+
+```sh
+$ pub global activate protoc_plugin
+```
+
+and follow the directions to add `~/.pub-cache/bin` to your PATH, if you haven't
+already done so.
+
+You can now regenerate the Dart files. Set the `PROTOBUF` and `GOOGLEAPIS`
+environment variables to point to your clone of
+[google/protobuf](https://github.com/google/protobuf) and
+[googleapis/googleapis](https://github.com/googleapis/googleapis), respectively,
+and then run
+
+```sh
+$ tool/regenerate.sh
+```

+# Description
+The hello world server and client demonstrate how to use Dart gRPC libraries to
+perform unary RPCs.
+
+See the definition of the hello world service in `protos/helloworld.proto`.
+
+# Run the sample code
+To compile and run the example, assuming you are in the root of the helloworld
+folder, i.e., .../example/helloworld/, first get the dependencies by running:
+
+```sh
+$ pub get
+```
+
+Then, to run the server:
+
+```sh
+$ dart bin/server.dart
+```
+
+Likewise, to run the client:
+
+```sh
+$ dart bin/client.dart
+```
+
+# Regenerate the stubs
+
+If you have made changes to the message or service definition in
+`protos/helloworld.proto` and need to regenerate the corresponding Dart files,
+you will need to have protoc version 3.0.0 or higher and the Dart protoc plugin
+version 0.7.9 or higher on your PATH.
+
+To install protoc, see the instructions on
+[the Protocol Buffers website](https://developers.google.com/protocol-buffers/).
+
+The easiest way to get the Dart protoc plugin is by running
+
+```sh
+$ pub global activate protoc_plugin
+```
+
+and follow the directions to add `~/.pub-cache/bin` to your PATH, if you haven't
+already done so.
+
+You can now regenerate the Dart files by running
+
+```sh
+$ protoc --dart_out=grpc:lib/src/generated -Iprotos protos/helloworld.proto
+```

+# Description
+The metadata server and client demonstrate how to handle custom metadata,
+cancellation, and timeouts in Dart gRPC.
+
+See the definition of the metadata service in `protos/metadata.proto`.
+
+# Run the sample code
+To compile and run the example, assuming you are in the root of the metadata
+folder, i.e., .../example/metadata/, first get the dependencies by running:
+
+```sh
+$ pub get
+```
+
+Then, to run the server:
+
+```sh
+$ dart bin/server.dart
+```
+
+Likewise, to run the client:
+
+```sh
+$ dart bin/client.dart
+```

+# Description
+The route guide server and client demonstrate how to use Dart gRPC libraries to
+perform unary, client streaming, server streaming and full duplex RPCs.
+
+See the definition of the route guide service in `protos/route_guide.proto`.
+
+# Run the sample code
+To compile and run the example, assuming you are in the root of the route_guide
+folder, i.e., .../example/route_guide/, first get the dependencies by running:
+
+```sh
+$ pub get
+```
+
+Then, to run the server:
+
+```sh
+$ dart bin/server.dart
+```
+
+Likewise, to run the client:
+
+```sh
+$ dart bin/client.dart
+```
+
+# Regenerate the stubs
+
+If you have made changes to the message or service definition in
+`protos/route_guide.proto` and need to regenerate the corresponding Dart files,
+you will need to have protoc version 3.0.0 or higher and the Dart protoc plugin
+version 0.7.9 or higher on your PATH.
+
+To install protoc with Dart support, take these steps:
+
+1. Install the `protoc` matching your development operating system from
+[the Protocol Buffers releases page](https://github.com/google/protobuf/releases)
+(e.g. `protoc-3.5.1-osx-x86_64.zip` for macOS).
+
+1. Get the Dart protoc plugin by running
+
+ ```sh
+ $ pub global activate protoc_plugin
+ ```
+
+1. Add `~/.pub-cache/bin` to your PATH, if you haven't
+already done so.
+
+You can now regenerate the Dart files by running
+
+```sh
+$ protoc --dart_out=grpc:lib/src/generated -Iprotos protos/route_guide.proto
+```

+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our
+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.

+# HTTP/2 for Dart
+
+This library provides an http/2 interface on top of a bidirectional stream of bytes.
+
+## Usage:
+
+Here is a minimal example of connecting to a http/2 capable server, requesting a resource and
+iterating over the response.
+
+```dart
+import 'dart:convert';
+import 'dart:io';
+
+import 'package:http2/http2.dart';
+
+main() async {
+ var uri = Uri.parse('https://www.google.com/');
+
+ var transport = new ClientTransportConnection.viaSocket(
+ await SecureSocket.connect(
+ uri.host,
+ uri.port,
+ supportedProtocols: ['h2'],
+ ),
+ );
+
+ var stream = transport.makeRequest(
+ [
+ new Header.ascii(':method', 'GET'),
+ new Header.ascii(':path', uri.path),
+ new Header.ascii(':scheme', uri.scheme),
+ new Header.ascii(':authority', uri.host),
+ ],
+ endStream: true,
+ );
+
+ await for (var message in stream.incomingMessages) {
+ if (message is HeadersStreamMessage) {
+ for (var header in message.headers) {
+ var name = utf8.decode(header.name);
+ var value = utf8.decode(header.value);
+ print('Header: $name: $value');
+ }
+ } else if (message is DataStreamMessage) {
+ // Use [message.bytes] (but respect 'content-encoding' header)
+ }
+ }
+ await transport.finish();
+}
+```
+
+An example with better error handling is available [here][example].
+
+See the [API docs][api] for more details.
+
+## Features and bugs

+/// This library provides an http/2 interface on top of a bidirectional stream
+/// of bytes.
+///
+/// The client and server sides can be created via [ClientTransportStream] and
+/// [ServerTransportStream] respectively. Both sides can be configured via
+/// settings (see [ClientSettings] and [ServerSettings]). The settings will be
+/// communicated to the remote peer (if necessary) and will be valid during the
+/// entire lifetime of the connection.
+///
+/// A http/2 transport allows a client to open a bidirectional stream (see
+/// [ClientTransportConnection.makeRequest]) and a server can open (or push) a
+/// unidirectional stream to the client via [ServerTransportStream.push].
+///
+/// In both cases (unidirectional and bidirectional stream), one can send
+/// headers and data to the other side (via [HeadersStreamMessage] and
+/// [DataStreamMessage]). These messages are ordered and will arrive in the same
+/// order as they were sent (data messages may be split up into multiple smaller
+/// chunks or might be combined).
+///
+/// In the most common case, each direction will send one [HeadersStreamMessage]
+/// followed by zero or more [DataStreamMessage]s.
+///
+/// Establishing a bidirectional stream of bytes to a server is up to the user
+/// of this library. There are 3 common ways to achive this
+///
+/// * connect to a server via SSL and use the ALPN (SSL) protocol extension
+/// to negotiate with the server to speak http/2 (the ALPN protocol
+/// identifier for http/2 is `h2`)
+///
+/// * have prior knowledge about the server - i.e. know ahead of time that
+/// the server will speak http/2 via an unencrypted tcp connection
+///
+/// * use a http/1.1 connection and upgrade it to http/2
+///
+/// The first way is the most common way and can be done in Dart by using
+/// `dart:io`s secure socket implementation (by using a `SecurityContext` and
+/// including 'h2' in the list of protocols used for ALPN).
+///
+/// A simple example on how to connect to a http/2 capable server and
+/// requesting a resource is available at https://github.com/dart-lang/http2/blob/master/example/display_headers.dart.
