Annotation for dart_native.

Automatic type conversion solution for dart_native based on source_gen through annotation.

1. Add build_runner package to dev_dependencies in your pubspec.yaml.

dev_dependencies:
  # Add this line
  build_runner:

2. Annotate a Dart wrapper class with @native. If this wrapper is generated by @dartnative/codegen, skip to next.

@native
class RuntimeSon extends RuntimeStub {
  RuntimeSon([Class isa]) : super(Class('RuntimeSon'));
  RuntimeSon.fromPointer(Pointer<Void> ptr) : super.fromPointer(ptr);
}

3. Annotate your own entry(such asmain()) with @nativeRoot:

@nativeRoot
void main() {
  runApp(App());
}

4. Run this command to generate files into your source directory:

flutter packages pub run build_runner build --delete-conflicting-outputs

Suggest you running the clean command before build:

flutter packages pub run build_runner clean

5. Call function generated in xxx.dn.dart:

@nativeRoot
void main() {
  // Function name is generated by name in pubspec.yaml.
  runDartNativeExample(); 
  runApp(App());
}

Add packages to dependencies in your pubspec.yaml example:

dependencies:
  dart_native_gen: any
