how to call dispatch action from a void method in flutter redux

[hkmsadek]

I am trying to perform a dispatch action from a method. Here is how I am trying

StoreConnector<AppState, AppState>(
                   converter: (store) => store.state,
                   builder: (context, items) => Column(
                      children: <Widget>[
                        Text(items.rahi),
                        Text(items.mySiteUrl),
                        RaisedButton(
                          child: Text('update rahi'),
                         onPressed: (){_updateRahi(store);},
                        ),
                      ],
                   )

                 ),

You can see I have cakked updateRahi method and inside this method

void _updateRahi(store){
  var text = status.text; 
  // want to call dispatch action from here
  store.dispatch('this is some texts');

}

Hey there -- please see the following discussion: #108

Essentially, you need to convert the Store into a ViewModel like so:

/// Just returns a function that takes in an integer and dispatches an `ItemSelectedAction`
StoreConnector<AppState, void Function(int selectedItemId)>(
  converter: (store) => (int selectedItemId) => store.dispatch(ItemSelectedAction(selectedItemId)),
  builder: (context, onItemSelected) => RaisedButton(
    child: Text("Press me!"),
    onPressed: () => onItemSelected(1),
  ),
);


/// More complex example with a "ViewModel"
class _ViewModel {
  final int itemId;
  final void Function() onItemSelected;

  _ViewModel(this.itemId, this.onItemSelected);
}

StoreConnector<AppState, _ViewModel>(
  converter: (store) {
    final itemId = store.state.getMeAnItemId;
    
    return _ViewModel(
      itemId,
      () => store.dispatch(ItemSelectedAction(itemId)),
    );
  },
  builder: (context, viewModel) => RaisedButton(
    child: Text("Displaying ${viewModel.itemId}"),
    onPressed: viewModel.onItemSelected,
  ),
);
