android studio flutter启动一直卡在“ Running gradle task ‘assembledebug‘ “的解决问题

解决问题：
1、修改项目中android/build.gradle文件
将buildscript.repositories下面的

//google()
//mavenCentral()
 
注释掉，改成
 
maven {
   allowInsecureProtocol = true
   url 'https://maven.aliyun.com/repository/google'
}
maven {
   allowInsecureProtocol = true
   url 'https://maven.aliyun.com/repository/jcenter'
}
maven {
   allowInsecureProtocol = true
   url 'http://maven.aliyun.com/nexus/content/groups/public'
}

allprojects.repositories同上修改

只需要在App项目工程的build.gradle中，使用allowInsecureProtocol属性(允许gradle使用"不安全"的仓库并且不报警告信息)即可

allowInsecureProtocol = true
