问题

Flutter项目安装到Android手机一直显示在assembledebug

原因

网络不好，gradle依赖下载不下来

解决方案

修改如下的文件

gradle-wrapper.properties

使用腾讯提供的gradle镜像下载

distributionUrl=https://mirrors.cloud.tencent.com/gradle/gradle-7.5-all.zip

build.gradle文件

将图片中标记出来的地方改为使用下面的镜像地址

    repositories {maven { url 'https://maven.aliyun.com/repository/google' }maven { url 'https://maven.aliyun.com/repository/jcenter' }maven { url 'https://maven.aliyun.com/repository/public/' }maven { url 'https://maven.aliyun.com/repository/central' }maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }maven {url 'https://maven.aliyun.com/nexus/content/groups/public/'}maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }mavenCentral()google()}

allprojects {repositories {maven { url 'https://maven.aliyun.com/repository/google' }maven { url 'https://maven.aliyun.com/repository/jcenter' }maven { url 'https://maven.aliyun.com/repository/public/' }maven { url 'https://maven.aliyun.com/repository/central' }maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }maven {url 'https://maven.aliyun.com/nexus/content/groups/public/'}mavenCentral()google()}
}

在上面两步做完以后，理论上就可以正常安装了。

1. Flutter项目启动一直卡在Running Gradle task ‘assembleDebug‘问题解决
2. flutter run长时间卡在Running Gradle task ”assembleDebug“…
