飞镖| Flutter Package：如何更新包不允许我的开发取得进展？

Question

以下包尚未更新：https://pub.dartlang.org/packages/tts我收到同样的错误。有什么办法我可以更新或解决这个问题在我这边继续https://pub.dartlang.org/packages/tts#-analysis-tab-

Running flutter packages pub upgrade failed with the following output:

ERR: The current Dart SDK version is 2.1.0-dev.1.0.flutter-69fce633b7.

Because tts requires SDK version >=1.8.0 <=2.0.0, version solving failed.

Answer 1

将其添加到pubspec.yaml

dependency_overrides:
  tts: ^1.0.1

直到tts更新为支持Dart 2决赛。
