1、問題：用安卓模擬器打開flutter項(xiàng)目時(shí)候，一直卡在Running Gradle task 'assembleDebug'...

2、原因：這是因?yàn)閍ndroid studio運(yùn)行項(xiàng)目時(shí)需要請(qǐng)求部分資源，而請(qǐng)求外網(wǎng)資源，你懂的...

3、解決：解決方法:1、翻*墻 。2換源

• flutter\packages\flutter_tools\gradle/flutter.gradle

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

class FlutterPlugin implements Plugin<Project> {
    // private static final String DEFAULT_MAVEN_HOST = "https://storage.googleapis.com";
    private static final String DEFAULT_MAVEN_HOST = "https://storage.flutter-io.cn";
...}

• flutter\packages\flutter_tools\gradle/resolve_dependencies.gradle

repositories {
    // google()
    // mavenCentral()
    maven { url 'https://maven.aliyun.com/repository/google' }
    maven { url 'https://maven.aliyun.com/repository/jcenter' }
    maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
    maven {
        // url "$storageUrl/download.flutter.io"
        url "https://storage.flutter-io.cn/download.flutter.io"
    }
}

• 項(xiàng)目中的android\build.gradle

buildscript {
    ext.kotlin_version = '1.6.10'
    repositories {
//        google()
//        mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public' }
    }

...

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