Question

About
Creating a flutter application, where I have updated
flutter SDK,
required packages in pubspec.yaml to the latest version, and
changes made to the android>app>build.gradle file
minSdkVersion 23
After performing all the steps mentioned above, I executed 3 commands...
flutter clean
flutter pub get
flutter run
And ultimately I am getting these Notes...
