由于国内 网络环境原因， 新建 flutter工程的 配置文件 需要修改几个地方，

1. gradle-wrapper.properties

问题：Exception in thread "main" java.net.ConnectException: Connection timed out: connect：

解决方法：修改为 国内镜像

 

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-7.6.3-all.zip

2. build.gradle

问题：Could not resolve all dependencies for configuration ':app:debugRuntimeClasspath'.

或者：

Using insecure protocols with repositories, without explicit opt-in, is unsupported. Switch Maven repository 'maven(XXX)' to redirect to a secure protocol (like HTTPS) or allow insecure protocols.

 

解决方法：修改为 国内镜像，并且配置信 任该镜像

allprojects {
    repositories {
//        google()
//        mavenCentral()
        maven {
            allowInsecureProtocol = true
            url 'https://mirrors.cloud.tencent.com/gradle/'
        }
        maven {
            allowInsecureProtocol = true
            url 'https://mirrors.cloud.tencent.com/nexus/repository/maven-public/'
        }
        maven {
            allowInsecureProtocol = true
            url 'https://maven.aliyun.com/repository/gradle-plugin' }
        maven {
            allowInsecureProtocol = true
            url 'http://maven.aliyun.com/nexus/content/groups/public' }
        maven {
            allowInsecureProtocol = true
            url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven {
            allowInsecureProtocol = true
            url 'https://maven.aliyun.com/repository/jcenter' }
        maven {
            allowInsecureProtocol = true
            url 'https://maven.aliyun.com/repository/google' }
    }
}
