【问题描述】：

当我尝试运行我的颤振项目时，我收到了这个错误。

Fluter 应用运行错误：任务 ':app:compileFlutterBuildDebug' 执行失败

调试：

Launching lib\main.dart on AOSP on IA Emulator in debug mode...
/C:/src/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_svg-0.18.1/lib/src/picture_provider.dart:50:59: Error: No named parameter with the name 'nullOk'.
        context != null ? Localizations.localeOf(context, nullOk: true) : null,

我的 main.dart 文件如下所示：

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Demo',
      theme: ThemeData(
        textTheme: Theme.of(context).textTheme.apply(bodyColor: kTextColor),
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: HomeScreen(),
    );
  }
}

有人知道怎么解决吗？

更新：在 pubspec.yaml 中运行 flutter pub get 并不能解决问题。

【问题讨论】：

这是您的错误：50:59：错误：没有名为“nullOk”的命名参数。上下文！=空？ Localizations.localeOf(context, nullOk: true) : null
它说它在颤振的源文件夹中。我不认为我可以编辑它？

按照以下步骤操作：

添加以下依赖或最新版本
