Mobx.dart: Implementation of multiple stores (communication between stores)

[dukaric1991]

How can i implement one parent store with multiple other stores, and use some observables in parent store and use some observable in store2 for example?

PARENT STORE:

import 'package:mobx/mobx.dart';
import 'store1.dart';
import 'store2.dart';

class ParentStore = ParentStoreBase with _$ParentStore;

abstract class ParentStoreBase implements Store {
@observable
  Store1 store1= new Store1();
@observable
  Store1 store2= new Store2();
@observable
  bool ParentLoading = false;
@action
  setParentLoading (bool value) {
    ParentLoading = value;
  }
}

STORE 2: (_how to communicate between stores or instantiate ParentStore to get to ParentStore observables/values?_)

import 'package:mobx/mobx.dart';
import 'parent_store.dart';

class Store2= Store2Base with _$Store2;

abstract class Store2Base implements Store {
@observable
  ParentStore parentStore= new ParentStore();
@observable
  bool value2= false;
@action
 setvalue2 (bool value) {
   if(parentStore.ParentLoading == true)
       value2 = value;
 }
}

One quick option is to pass the ParentStore as constructor argument into your child stores

[dukaric1991]

And how would passing ParentStore trough constructor look like in code? If you could give me an example?

And maybe you could add this too Examples for future users :)

Only showing the relevant parts:

// store2.dart
abstract class Store2Base implements Store {
  Store2Base({this.parent}); // store the parent

  final ParentStore parent;

  @observable
  bool value2= false;

  @action
  setvalue2 (bool value) {
    if(parent.ParentLoading == true)
      value2 = value;
  }
}

// parent.dart
abstract class ParentStoreBase implements Store {
  ParentStoreBase(){
    this.store1 = Store1(parent: this); // pass the parent
  }

  @observable
  Store1 store1;

  @observable
  bool ParentLoading = false;

  @action
  setParentLoading(bool value) {
    ParentLoading = value;
  }
}

Thanks for quick feedback, it works like charm!

@pavanpodila Doesn't that cause type errors? ParentStoreBase is not a ParentStore.
