Flutter pub get version 解决失败

Question

我遇到了 flutter pub get 的问题，尝试更新 dart sdk，重启电脑以将 Dart sdk 位置添加回环境变量，删除 .git 文件夹。

Running "flutter pub get" in calculator...
The current Dart SDK version is 2.13.4.

Because calculator depends on webview_flutter >=2.0.14 which requires SDK version >=2.14.0 <3.0.0, version solving failed. pub get failed (1; Because calculator depends on webview_flutter >=2.0.14 which requires SDK version >=2.14.0 <3.0.0, version solving failed.) exit code 1

Answer 1

将 pubspec.yaml 中 webview_flutter 的版本更改为 webview_flutter: any

Answer 2

当您说您尝试更新 Dart SDK 时，您是否也更新了 pubspec.yaml？

environment:
  sdk: ">=2.14.0 <3.0.0"

Answer 3

尝试删除 pubspec.lock 然后重试

Answer 4

更新Dart Sdk并重启电脑后问题解决了。即使在这两个步骤之后我仍然遇到相同的错误，所以我将 any 放在 pubspec.yaml 和运行 flutter pub get 之前的包值中，我关闭了我的杀毒软件。

Answer 5

尝试

flutter upgrade
