Chapter 2 flutter apprentice book error

🎤 General Discussion Flutter

I’m encountering an issue while building my Flutter application. When attempting to build the project, I’m getting the following warnings:

warning: [options] source value 8 is obsolete and will be removed in a future release
warning: [options] target value 8 is obsolete and will be removed in a future release
warning: [options] To suppress warnings about obsolete options, use -Xlint:-options.
3 warnings

But more importantly, an error is preventing a successful build:

ERROR:E:\NewApp\third_app\build\path_provider_android\intermediates\runtime_library_classes_jar\debug\classes.jar: D8: java.lang.NullPointerException: Cannot invoke “String.length()” because “” is null

This error seems to be related to path_provider_android and occurs during the ‘:app:mergeDexDebug’ task. I’m using Flutter with a specific version of the Android Gradle Plugin (7.3.0).

Do you have any suggestions on how to resolve this error and get the project to compile successfully?

Thank you in advance for your assistance.
