Flutter 运行Flutter run 出现的问题 flutter

1最近公司开发新的项目，于是新建了一个flutter项目。运行Flutter项目执行flutter run命令后卡住了，一直停留在Running Gradle task 'assembleDebug'...
需要在，android项目下找到build.gradle文件。更改为阿里的镜像：

repositories { maven { url 'https://maven.aliyun.com/repository/google' } maven { url 'https://maven.aliyun.com/repository/jcenter' } maven { url 'http://maven.aliyun.com/nexus/content/groups/public' } //google() //jcenter() }allprojects { repositories { maven { url 'https://maven.aliyun.com/repository/google' } maven { url 'https://maven.aliyun.com/repository/jcenter' } maven { url 'http://maven.aliyun.com/nexus/content/groups/public' } //google() //jcenter() } }

2然后我更改了如上代码后再次执行flutter run后报了如下错误：

[!] Gradle threw an error while downloading artifacts from the network. Retrying to download... Running Gradle task 'assembleDebug'... Exception in thread "main" java.util.zip.ZipException: error in opening zip file

解决上面的错误需要找到android项目中的gradle下面的gradle-wrapper.properties。将gradle的版本改了一下
改成我之前电脑中有的gradle版本。我这里将原来的gradle-5.6.2改成了gradle-6.1.1

3之后运行项目报出了如下问题：
