gradle 问题 https://cloud.tencent.com/developer/article/1723914

问题出在 路径/flutter/packages/flutter_tools/gradle/flutter.gradle 里 tools 版本不对

  dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
    }

# 问题

CocoaPods's specs repository is too out-of-date to satisfy dependencies.

Go to /ios folder inside your Project.
Delete Podfile.lock
Run pod install --repo-update
Run flutter clean
Once complete, rebuild your Flutter application: flutter run

Exception in thread "main" java.util.zip.ZipException: error in opening zip file

Go to flutter_app>android> and delete gradle folder, delete gradlew files and run the app again using flutter run

I just ran flutter upgrade and flutter clean and it solved this issue in my case.
