Android：Gradle Issue - Flutter / Dart

　　Issue：

　　"Minimum supported Gradle version is 4.6. Current version is 3.3."

 

　　I have a problem with my Gradle Sync. I use Android Studio to build a Flutter / Dart App.

Errortext =>

* Error running Gradle:
ProcessException: Process "F:\flutter_map\android\gradlew.bat" exited abnormally:

BUILD FAILED

Total time: 3.6 secs


FAILURE: Build failed with an exception.

* Where:
Build file 'F:\flutter_map\android\app\build.gradle' line: 14

* What went wrong:
A problem occurred evaluating project ':app'.
> Failed to apply plugin [id 'com.android.application']
   > Minimum supported Gradle version is 4.6. Current version is 3.3. If using the gradle wrapper, try editing the distributionUrl in F:\flutter_map\android\gradle\wrapper\gradle-wrapper.properties to gradle-4.6-all.zip

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
  Command: F:\flutter_map\android\gradlew.bat app:properties

Finished with error: Please review your Gradle project setup in the android/ folder.

 

　　Solution：

　　try editing the distributionUrl in F:\flutter_map\android\gradle\wrapper\gradle-wrapper.properties to gradle-4.6-all.zip

 

　　即打開項目目錄下 \android\gradle\wrapper\gradle-wrapper.properties 文件，將

distributionUrl=https\://services.gradle.org/distributions/gradle-3.3-all.zip

　　修改成所需版本：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
