writeFlutterApi method

@override void writeFlutterApi(DartOptions generatorOptions, Root root, Indent indent, AstFlutterApi api, { String channelNameFunc(Method)?, bool isMockHandler = false, required String dartPackageName, })

Writes the code for host Api, api. Example: class FooCodec extends StandardMessageCodec {...}

abstract class Foo { static const MessageCodec<Object?> codec = FooCodec(); int add(int x, int y); static void setUp(Foo api, {BinaryMessenger? binaryMessenger}) {...} }
