最新的 Flutter 开发版本有很多错误答案

【问题标题】：Lots of error with latest Flutter dev release最新的 Flutter 开发版本有很多错误
【发布时间】：2021-05-21 01:37:22
【问题描述】：

我不确定我使用的哪个版本可以正常工作（但在 Channel master 之前，1.26.0-2.0.pre.86），但是因为我从 stable 切换到 dev 通道以处理 Web 项目我得到了很多错误..主要是js: ^0.6.1+1、intl: ^0.16.0和firebase: ^7.3.2 packages. Now, I solved the intl 取决于来自sdk的flutter_localizations，它依赖于intl 0.17.0，需要intl 0.17.0。by overriding it withintl: ^0.17 .0-nullsafety.2`，但我仍然从 js 和 firebase 包中得到大量错误，我将它们用于 web，因为官方包还没有 web 对应项。你知道这只是一些软件包没有为最新的 Flutter 版本做好准备，还是需要修复其他的东西？一如既往，非常感谢您的帮助。错误：

使用稳定的通道1.22.2可能不会出错
但是稳定频道不是为网络构建的，对吧？

终于找到问题了。这当然是由于cloud_firestore 包的更新。因为它现在有与firebase 包冲突的网络版本。最新的兼容版本是cloud_firestore: 0.14.0，在远程配置也将有一个网络版本之前，我一直坚持使用firebase 包作为我的应用程序的网络版本..

Firebase 的初始化方法也不同：新的不工作：

class MyApp extends StatelessWidget {
  final Future<FirebaseApp> _initialization = Firebase.initializeApp();
  @override
  Widget build(BuildContext context) {
//    Locale myLocale = Localizations.localeOf(context);

  return FutureBuilder(
    future: _initialization,
      builder: (context, snapshot){
        if(snapshot.hasError){

        }
        if (snapshot.connectionState == ConnectionState.done){
          return MaterialApp(

...

旧工作：

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  BlocSupervisor.delegate = SimpleBlocDelegate();
  setupLocator();
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
//    Locale myLocale = Localizations.localeOf(context);
    return MaterialApp(
...

希望它对其他人有所帮助，因为 Firebase 总是通过几乎所有更新来破坏代码..

我面临类似的错误flutter/packages/flutter/lib/src/foundation/_platform_web.dart 找不到导入'dart：html' 我发现我没有为我的项目启用 web，而我使用的包是用于 web 使用的，这会导致问题，它要么在你的项目中初始化 web 构建，要么找出导致问题的包

试试flutter create .
