Fix Flutter Error : Cannot resolve symbol for properties and Gradle exception
Have a problem on Cannot resolve symbol for properties and Gradle exception.
Follow with me :
1-
File : Project Structure
Under Project Settings/Project : Set Project SDK to Android API 29 Platform
2-
here should be a notification stating there is an invalid item in the dependencies list under Project Structure/Problems. If there is, go to :
Project Structure
Under Project Settings/Modules
select app_name_android
Dependencies tab
choose the latest "Android API 29 Platform" in the Module SDK box.
3-
Update GradleException() to FileNotFoundException() under android/app/build_gradle since it's not supported in the Java version of Android API 29.
