如何解决颤动中的版本控制

How to resolve versioning in flutter

我想将 url_launcher 包添加到 flutter 中的 pubspec.yml 文件。

代码 pubspec.yml

name: url_launch_app
description: A new Flutter application.


version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter
  #url_launcher: '>=0.1.2 <0.2.0'
  url_launcher: '^0.4.1'

我已经为 url_laucher 添加了包,但是当我点击 packages get 时,我遇到了以下错误。

错误:

Running "flutter packages get" in url_launch_app…

The current Dart SDK version is 2.3.0-dev.0.1.flutter-cf4444b803.

Because url_launch_app depends on url_launcher >=0.1.1 <3.0.0 which requires SDK version <2.0.0, version solving failed.

pub get failed (1)
Process finished with exit code 1

如何解决这个版本控制错误?

替换你的

url_launcher: '^0.4.1'

来自

url_launcher: ^5.0.2
