iOS版本更新Flutter 1.22和Firebase插件


动机

Flutter 1.22已声明它将支持iOS 14，并且firebase_crashlytics现在与Firebase Crashlytics SDK兼容，因此我想更新可以更新的内容

下载Xcode 12

Xcode12是必需的，因此请下载。
您可以从此处

下载适当的Xcode。

https://developer.apple.com/download/more/

1
[?] Xcode - develop for iOS and macOS (Xcode 12.0.1)

Flutter更新

首先，我们将更新Flutter

1
$ flutter upgrade

在更新时，以下版本

1
[?] Flutter (Channel stable, 1.22.0, on Mac OS X 10.15.6 19G73, locale ja-JP)

重新创建Podfile

我认为这取决于创建项目的时间，但是
使用较旧版本的Flutter创建的Podfile应该删除并重新创建。
如果删除它并快速运行，将创建一个新的podfile。

根据项目的不同，您可能已将设置添加到Podfile，因此请进行必要的修改。
当有多个Xcode构建设置和与Firebase插件相关的修补程序时，可能会有设置。

2
$ rm ios/Podfile
$ flutter run

插件更新

为了更新

firebase_crashlytics，还必须更新firebase_core，并且必须提供所有结果，因此结果为以下版本。

pubspec.yaml

  # Firebase
  firebase_core: 0.5.0
  firebase_auth: 0.18.1+1
  firebase_crashlytics: 0.2.1
  firebase_messaging: 7.0.2
  firebase_ml_vision: 0.9.7
  firebase_dynamic_links: 0.6.0+1
  firebase_analytics: 6.0.1

即使您按原样正常进行操作，它也会与Xcode构建混淆，因此我们将支持它。
Firebase插件仍然很旧，并且有新版本
似乎发生了未按预期下载且依赖项解析失败的情况。
(由于我在这里花了很多时间，执行顺序非常可疑，可能会有不必要的命令

$ flutter clean
$ cd ios && rm -rf Pods/
$ flutter packages upgrade
$ pod update && pod install

此外，由于iOS8已从Xcode 12的Deployment Target中删除，因此在构建时将输出大量警告，因此请相应地更改库的Deployment Target。

与新小部件

冲突

Flutter 1.22中添加了以下按钮小部件，但
因为项目中已经有一个名为TextButton的自定义小部件。
我们采取了重命名等必要措施。

flutter_stetho

我正在使用stetho作为应用程序的通信系统的调试工具，但是由于此插件不支持Flutter 1.22，因此我将导入受支持的修改后的分支。
(PR已发布，因此，如果已导入，则可以正常更新

此更新花费了很多时间，所以我组织了所做的事情。
我希望这对将来会做出回应的人有所帮助。
顺便说一下，接下来是Android支持！
