Some input files use or override a deprecated API Flutter build android

Question

I have a flutter project and I want to build it in android studio. I build it with this command in the terminal:

flutter build apk --release

I'm getting this error report:

Note: C:\Users\Jovik\AppData\Roaming\Pub\Cache\hosted\pub.dartlang.org\path_provider-1.5.1\android\src\main\java\io\flutter\plugins\pathprovider\PathProviderPlugin.java uses or overrides

    setupChannel(binding.getFlutterEngine().getDartExecutor(), binding.getApplicationContext());

I'm not a flutter developer so I have no special knowledge of these technologies. I have upgraded flutter and the flutter doctor did not find any error what problem? Could you help me too? Give advice on what I’m doing wrong.

Solution

This is a known issue with the shared_preferences plugin with flutter. This issue has been addressed about 20 days ago. Make sure that you are using the newest version of shared_preferences (0.5.6+3) and update to reflect this in your pubspec.yaml.

Try running flutter clean and then also running flutter upgrade.
