鸿蒙-flutter 混合开发

步骤

• flutter create --template=module my_flutter_module
• flutter clean
• flutter pub get
• 签名: 模拟器或真机
• flutter build har
• 新建ohos_app工程
• 导入Har包 (点击 Clean Project, 点击 Sync and Refresh Project)
• 修改配置文件: /oh-package.json5
• 修改配置文件: /entry/oh-package.json5
• 修改文件: EntryAbility, FlutterContainerPage,Index
• 签名运行真机

flutter create --template=module my_flutter_module
flutter clean
flutter pub get
flutter build har

"overrides": {
   "@ohos/flutter_ohos": "file:./har/flutter_embedding_release.har",

}

EntryAbility

import { FlutterAbility, FlutterEngine } from '@ohos/flutter_ohos';
import { GeneratedPluginRegistrant } from '@ohos/flutter_module';

export default class EntryAbility extends FlutterAbility {
  configureFlutterEngine(flutterEngine: FlutterEngine) {
    super.configureFlutterEngine(flutterEngine)
    GeneratedPluginRegistrant.registerWith(flutterEngine);
  }
}

index

import { router } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  build() {
    Column() {
      Text('Hello World').fontSize('50fp').fontWeight(FontWeight.Bold)
      Blank().height(80)
      Button('跳转Flutter').onClick(() => {
        router.pushUrl({ url: 'pages/FlutterContainerPage'})
      })
    }.justifyContent(FlexAlign.Center)
    .alignItems(HorizontalAlign.Center)
    .width('100%')
    .height('100%')
  }
}

FlutterContainerPage

import { FlutterEntry, FlutterPage, FlutterView } from '@ohos/flutter_ohos'

@Entry
@Component
struct FlutterContainerPage {

  private flutterEntry?: FlutterEntry;
  private flutterView?: FlutterView;

  aboutToAppear() {
    this.flutterEntry = new FlutterEntry(getContext(this));
    this.flutterEntry.aboutToAppear();
    this.flutterView = this.flutterEntry.getFlutterView();
  }

  aboutToDisappear() {
    this.flutterEntry?.aboutToDisappear();
  }

  onPageShow() {
    this.flutterEntry?.onPageShow();
  }

  onPageHide() {
    this.flutterEntry?.onPageHide();
  }

  build() {
    RelativeContainer() {
      FlutterPage({ viewId: this.flutterView?.getId()})
    }
  }
}
