我想将url_launcher
包添加到pubspec.yml
文件中flutter
。
pubspec.yml 的代码
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,但是单击时packages get
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
如何解决此版本控制错误?
