Flutter编译卡在Running Gradle task ‘assembleDebug

1、翻墙

2、修改国内镜像源（以下以Flutter 3.19.3版本为例）

1. 找到Flutter SDK目录下的Flutter配置文件resolve_dependencies.gradle

        路径：flutter/packages/flutter_tools/gradle/resolve_dependencies.gradle

        1)、第一处修改：

                google()

                mavenCentral()

               改为:

                maven { url 'https://maven.aliyun.com/repositindex.php/tags-1038.html" >ory/central' }

                maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

                maven { url 'https://maven.aliyun.com/repository/google' }

                maven { url 'https://maven.aliyun.com/repository/public'}

        2)、第二处修改：

                url "$storageUrl/${engineRealm}download.flutter.io"

                改为：url "https://mirrors.tuna.tsinghua.edu.cn/flutter/download.flutter.io"

       2. 找到Flutter SDK目录下的Flutter配置文件flutter.groovy

        地址为： flutter/packages/flutter_tools/gradle/src/main/groovy

                1）、第一处修改

                google()

                mavenCentral()

               改为:

                maven { url 'https://maven.aliyun.com/repository/central' }

                maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

                maven { url 'https://maven.aliyun.com/repository/google' }

                maven { url 'https://maven.aliyun.com/repository/public'}

                2）、第二处修改

                DEFAULT_MAVEN_HOST = "https://storage.googleapis.com";        

                改为：DEFAULT_MAVEN_HOST = "https://mirrors.tuna.tsinghua.edu.cn/flutter"

        3.修改项目根目录下Android/build.gradle文件镜像地址

                google()

                mavenCentral()

               改为:

                maven { url 'https://maven.aliyun.com/repository/central' }

                maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }

                maven { url 'https://maven.aliyun.com/repository/google' }

                maven { url 'https://maven.aliyun.com/repository/public'}

        4.修改项目gradle下载地址 

            路径：项目根目录/android/gradle/wrapper/gradle-wrapper.properties

                改：

        https\://services.gradle.org/distributions/gradle-xx.zip

                为：

        https://mirrors.cloud.tencent.com/gradle/gradle-xx.zip
