  <blockquote>
    <p>Finished with error: Please review your Gradle project setup in the
    android/ folder.
    * Error running Gradle: ProcessException: Process "C:\Users\Almoit PC\Desktop\MyApp\Map\flutter_app2\android\gradlew.bat" exited

    WARNING: The specified Android SDK Build Tools version (27.0.3) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.2.1.
    Android SDK Build Tools 28.0.3 will be used.
    To suppress this warning, remove "buildToolsVersion '27.0.3'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.</p>
    
    <p>FAILURE: Build failed with an exception.</p>
    
    <ul>
    <li><p>What went wrong: The Android Gradle plugin supports only Kotlin Gradle plugin version 1.2.51 and higher. Project 'android' is using
    version 1.1.2-4.</p></li>
    <li><p>Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.</p></li>
