Flutter 開發運行前兩步

Failed to send crash report due to a network error: SocketException: OS Error: 信號燈超時時間已到 , errno = 121, address = clients2.google.com, port = 55220

flutter run 時出現上面的錯誤

須要修改兩個地方

build.gradle文件內修改爲國內鏡像

buildscript {
    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'}
        
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

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'}
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

另外一個文件須要下載好壓縮包到本地而後應用路徑修改成本身的路徑

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip

改成

distributionUrl=file:///D:/Android/gradle-4.10.2-all.zip

再次flutter run 正常
