Flutter pub 多次失败

Question

我尝试了“flutter pub get”，这是消息：

Because flash_chat depends on flutter any from sdk which doesn't exist (unknown SDK "flutterx"), version solving failed.
pub get failed (server unavailable) -- attempting retry 2 in 2 seconds...

注意：flutter doctor 工作没有问题

Answer 1

请检查一次您的互联网连接。

Answer 2

您在 pubspec.yaml 中有错字。 flutter 依赖项应如下所示：

dependencies:
  flutter:
    sdk: flutter

如果您不小心将其更改为 sdk: flutterx，则会收到您报告的错误消息。
