CodePudding user response：

How I solved my problem by following the below method:

remove the problem making package from /.pub-cache/hosted/pub.dartlang.org

Run flutter pub get change this:

distributionUrl=https://services.gradle.org/distributions/gradle-5.6.2-all.zip to this:

distributionUrl=https://services.gradle.org/distributions/gradle-6.5-all.zip and then in project-folder/buil.gradle

change this:

classpath 'com.android.tools.build:gradle:3.5.0' to this:

classpath 'com.android.tools.build:gradle:4.1.1' and then run this command

flutter clean build or run your project, good luck.
