Dart components can be compiled in various different compilation modes. The component can either be compiled in JIT mode or AOT mode and each of these can optionally be compiled in ‘product’ mode which runs in a stripped down VM. By default, the dart_component will pick the compilation mode based on the following:
The compilation mode can be set explicity as a gn arg by setting the
Product mode can be set by setting the
dart_force_product variable to true.
Flutter components and Dart components share much of the same functionality and only differ in their runners and some dependencies. The dart_component will delegate much of the work to the flutter_dart_component target which resides at //build/flutter/internal/flutter_dart_component.gni. The dart_component just sets up the runner dependencies before forwarding to the flutter_dart_component target.
