Flutter 启动运行的时候报错：

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:url_launcher
 - package:url_launcher_platform_interface
 - package:plugin_platform_interface

For solutions, see https://dart.dev/go/unsound-null-safety

Command PhaseScriptExecution failed with a nonzero exit code

解决方案：

可以直接在命令行中执行

flutter run --no-sound-null-safety

 也可以到Android studio中去设置运行配置

首先打开Edit Configurations 页面

然后在Additional run args 这行键入一下命令

--no-sound-null-safety

 如图所示

然后点击OK，再次重新运行就可以了

打开Android Studio，然后依次选择【Run】 -->【 Edit Configurations】 --> 【Add Additional Run args 】–> 【–no-sound-null-safety】，如下图。上面的问题是，这些包不支持 safety模式。我们可以在运行的时候添加。然后，再次运行就没有错误了。

从Flutter 2开始，Flutter便在配置中默认启用了空安全，通过将空检查合并到类型系统中，可以在开发过程中捕获这些错误，从而防止再生产环境导致的崩溃。如果当前项目开启了空安全，而引入的三方插件没有适配的话运行回报如下错误。 Error: Cannot run with sound null safety, because the following dependencies don't support null safety: - package:provider For solutions,

在Flutter中引入第三方库报错Cannot run with sound null safety, because the following dependencies。这是出现了don’t support null safe的问题，因为在Flutter2中使用了null safety（空安全）技术，如果出现null,就会报错。这种安全机制大大减少了null error。解决办法如下： 在终端运行flutter run --no-sound-null-safety “Edit Configuratio

开发过程中，有些图片是要放到本地资源文件中，然后本地加载，这样做需要两个步骤就可以实现 1.创建本地资源文件夹Images,然后添加图片 1.jpg,  2.jpg 2.配置pubspec.yaml 中的资源路径，必须配置，如果不配置，在程序中图片就会加载不出来 3.使用 Image.asset("images/1.jpg",width:500,height:50) 加载图片    ...

Error (Xcode): Error: Cannot run with sound null safety, because the following dependencies
05-26
It seems like you are experiencing an error with sound null safety in Xcode. This error typically occurs when you are using packages or dependencies that do not support sound null safety. To fix this error, you should update the dependencies in your project to their latest versions that support sound null safety. You can check if a package supports sound null safety by looking at its documentation or by checking its pub.dev page. If you are still having issues after updating your dependencies, you can try disabling sound null safety for your project. To do this, add the following line to your `pubspec.yaml` file: ``` environment: sdk: ">=2.12.0 <3.0.0" ``` This will allow your project to run without sound null safety. However, it is recommended that you update your dependencies to support sound null safety to ensure the stability and security of your project.
