It may be happened when you have multiple gradle in one project, the solution is just recheck your gradle.properties, delete the old one, and use the newest one

gradle-4.10.1

Next, follow this steps :

1. Use the newest gradle version and delete the others
2. File > Invalidate Caches, Restart
3. Build > Clean Project or flutter clean
4. File > Sync with All System
5. Add this path in gradle-wrapper.properties distributionUrl=https://services.gradle.org/distributions/gradle-4.10.1-all.zip
6. See the logcat and find the error, in the above we can see that library PackageInfo has deprecated (PackageInfo.java uses unchecked or unsafe operations). So, fix it by using the newest version of that library (check in https://pub.dartlang.org). Use and install it. Run packages get. Done.
7. Now run again the project
