Flutter 第一次运行,卡在Running Gradle task ‘assembleDegug‘,然后就提示错误的解决方案。_running gradle task 'assembledebug'...

Running Gradle task 'assembleDebug'...
 
FAILURE: Build failed with an exception.
 
* What went wrong:
A problem occurred configuring root project 'android'.
> Could not resolve all dependencies for configuration ':classpath'.
   > Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven3(http://maven.aliyun.com/nexus/content/groups/public)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols. See https://docs.gradle.org/7.5/dsl/org.gradle.api.artifacts.repositories.UrlArtifactRepository.html#org.gradle.api.artifacts.repositories.UrlArtifactRepository:allowInsecureProtocol for more details.
 
* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

需要修改您的项目 ：/{you Project}/android/gradle/build.gradle文件。如下图

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
//        google()
