原有的原生flutter项目如何迁移到鸿蒙?
1、创建个新项目，把旧项目的lib与assets目录复制覆盖到新项目 2、修改pubspec.yaml依赖,改为支持 鸿蒙版本 3、如果编译没问题理论上就能跑在鸿蒙设备上了 4、Android或iOS平台上的一些特殊修改复制到新项目 以上操作相对简单一些。如果在老项目里面改也是可以的，直接在项目根目录直行
flutter create --platforms ohos .
然后修改pubspec.yaml依赖
flutter pub get
flutter build hap
flutter build app 输出的app文件路径不对
flutter build app 输出的app文件所在位置 ohos/build/outputs/default/ohos-default-signed.app flutter build app --flavor myflavor 输出的app文件所在位置为 ohos/build/outputs/myflavor/ohos-myflavor-signed.app
Windows模拟器上运行flutter应用
- Windows环境上的鸿蒙模拟器上运行flutter应用
- 确保在切换编译架构类型后，libapp.so能被删除
使用命令:
flutter run -d 127.0.0.1:5555 --debug
flutter run -d 127.0.0.1:5555 --profile
flutter run -d 127.0.0.1:5555 --release
flutter build hap --target-platform ohos-x64 --debug
flutter build hap --target-platform ohos-x64 --profile
flutter build hap --target-platform ohos-x64 --release
注意事项：
更新后，在Windows环境的鸿蒙模拟器上运行flutter应用，如果遇到闪退情况，请在执行以下操作后再尝试重新运行：
- 删除 flutter_flutter/bin/cache 目录
- 运行 flutter clean 命令
