如何在nativescript中从app事件调用组件方法

import { Component } from "@angular/core";

@Component({
  selector: "app-component",
  template: "<Label text='Hello World'></Label>"
})
export class AppComponent {
  public onAppStart() {
    console.log("App started");
    // 在这里执行你的逻辑
  }
}

import { platformNativeScriptDynamic } from "@nativescript/angular";
import { AppModule } from "./app.module";
import { AppComponent } from "./app.component";
import { Application } from "@nativescript/core";

platformNativeScriptDynamic().bootstrapModule(AppModule).then(() => {
  Application.on(Application.launchEvent, () => {
    const appComponent = new AppComponent();
    appComponent.onAppStart();
  });
});
