I have no idea what you are talking about. If you want to save a list of “favorites”, create a “favorites” object and put the IDs or objects of what you favorite in there, save it. Then yu can read it and check if the currently displayed item is in that list.
Here is Example of local storage
app.module.ts file
import { IonicStorageModule } from '@ionic/storage';
// ...
@NgModule({
declarations: [
// ...
],
imports: [
IonicModule.forRoot(MyApp),
IonicStorageModule.forRoot()
],
bootstrap: [IonicApp],
entryComponents: [
// ...
],
providers: []
})
export class AppModule {}
your component file
import { Storage } from '@ionic/storage';
export class MyApp {
constructor(private storage: Storage) {
// set a key/value
this.storage.set('name', 'Max');
// Or to get a key/value pair
storage.get('age').then((val) => {
console.log('Your age is', val);
});
}
}
nextbtn() {
console.log(this.SignUpData.username);
this.storage.set('username', this.SignUpData.username);
}
readUsername() {
// Notice that the get method returns a promise!
storage.get('username').then((username) => {
console.log(username);
});
}
Hope, this will solve your issue
Thanks,
