Dart :如何忽略omit_local_variable_types警告？

dart compile aot my_app.dart --omit-local-variable-types

flutter:
  uses-material-design: true
  generate: true
  builder: flutter
  build-mode: release
  compile-options:
    - omit-local-variable-types

import 'package:flutter/foundation.dart';

void main() {
  debugDefaultTargetPlatformOverride = TargetPlatform.fuchsia;
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

android {
  ...
  buildTypes {
    release {
      dartOptions {
        args << '-OmitLocalVariableTypes'
      }
    }
  }
}
