· 阅读需 1 分钟
flutter 开发常见问题 Flutter 问题通常与 SDK、Dart、Gradle、Android 工具链和依赖版本共同相关。提交或记录故障时，应附上 flutter doctor、完整错误堆栈和可复现步骤。
- 下载flutter
windows 下载
https://storage.googleapis.com/flutter_infra_release/releases/stable/windows/flutter_windows_3.29.2-stable.zip
- 环境变量配置
FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
PUB_HOSTED_URL=https://pub.flutter-io.cn
- 排查Running Gradle task 'assembleDebug'...慢问题
cd android
.\gradlew.bat clean
查看那个下载慢，就把对应的包放到.gradle\caches\modules-2\files-2.1\
例如：kotlin-compiler-embeddable 1.8.22
目录：org.jetbrains.kotlin\kotlin-compiler-embeddable\1.8.22\d539a5dfaa4137bfdfec1322f569e8797da51d21
- gradle-wrapper 镜像配置
#distributionUrl=https\://services.gradle.org/distributions/gradle-8.10.2-all.zip
distributionUrl=https\://mirrors.cloud.tencent.com/gradle/gradle-8.10.2-all.zip
- gradle maven镜像配置
android\build.gradle.kts
maven { url=uri("https://mirrors.tencent.com/nexus/repository/maven-public/") }
- flutter命令行创建项目
flutter create my_app
