Error: Cannot run with sound null safety, because the following dependenciesdon‘t support null safe

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.
