knowa_flutter_bindings 2.2.0

The Flutter classes a Knowa code-push patch can use, bound for Knowa's patch runtime. You do not depend on it directly: knowa_sdk does.

example/example.dart

// Builds a widget from a patch using the Flutter bindings.
//
// Patches are normally compiled from Dart source by the Knowa CLI, and
// knowa_sdk registers these bindings for you. This example builds the
// compiled form of the following patch by hand:
//
//   @KnowaOverride('home.title')
//   Widget title() => const Text('Hello from a patch');
