Flutter更新后GoRouterState无queryParameters属性报错求助

之前使用Xcode测试应用一切正常，更新Flutter后出现报错，尝试论坛上所有解决方案仍未解决，无法为iPhone 15 Pro Max模拟器构建并启动应用。

报错信息 #

Error (Xcode): lib/flutter_flow/nav/nav.dart:383:14: Error: The getter 'queryParameters' isn't defined for the class 'GoRouterState'.

报错代码片段 #

extension _GoRouterStateExtensions on GoRouterState {
  Map<String, dynamic> get extraMap =>
      extra != null ? extra as Map<String, dynamic> : {};
  Map<String, dynamic> get allParams => <String, dynamic>{}
    ..addAll(pathParameters)
    ..addAll(queryParameters)
    ..addAll(extraMap);
  TransitionInfo get transitionInfo => extraMap.containsKey(kTransitionInfoKey)
      ? extraMap[kTransitionInfoKey] as TransitionInfo
      : TransitionInfo.appDefault();
}

class FFParameters {
  FFParameters(this.state, [this.asyncParams = const {}]);

  final GoRouterState state;
  final Map<String, Future<dynamic> Function(String)> asyncParams;

  Map<String, dynamic> futureParamValues = {};

• 确认GoRouter版本兼容性：报错源于GoRouter的API变更，GoRouterState的queryParameters方法在新版本中被移除，需检查项目中go_router的版本是否适配当前Flutter SDK。可在pubspec.yaml中锁定或升级go_router到兼容版本。
• 替换API调用：若无法升级go_router，可将代码中的queryParameters替换为uri.queryParameters（GoRouterState自带uri属性，可通过它获取查询参数），修改后的代码如下：

  Map<String, dynamic> get allParams => <String, dynamic>{}
    ..addAll(pathParameters)
    ..addAll(uri.queryParameters)
    ..addAll(extraMap);
  

• 清理缓存并重建：执行以下命令清除缓存，避免旧依赖残留影响构建：

  flutter clean
  flutter pub get
  cd ios && pod install && cd ..
  flutter run
  

• 替换废弃依赖：shared_preferences_ios已被废弃，需在pubspec.yaml中替换为shared_preferences_foundation：

  shared_preferences_foundation: ^2.3.4
  

  同时移除shared_preferences_ios的依赖声明。
• 逐步升级兼容依赖：对于无法直接升级的依赖（如google_fonts、package_info_plus），可尝试逐个升级，每次升级后执行flutter pub get并测试，避免版本冲突。
