VmFactory<St, T> class

Factory that creates a view-model of type Vm, for the StoreConnector:

return StoreConnector<AppState, _ViewModel>(
     vm: _Factory(),
     builder: ...

You must override the fromStore method:

class _Factory extends VmFactory {
   _ViewModel fromStore() => _ViewModel(
       counter: state,
       onIncrement: () => dispatch(IncrementAction(amount: 1)));
}

If necessary, you can pass the StoreConnector widget to the factory:

return StoreConnector<AppState, _ViewModel>(
     vm: _Factory(this),
     builder: ...

...
class _Factory extends VmFactory<AppState, MyHomePageConnector> {
   _Factory(widget) : super(widget);
   _ViewModel fromStore() => _ViewModel(
       counter: state,
       onIncrement: () => dispatch(IncrementAction(amount: widget.amount)));
}

Constructors

VmFactory([T widget])

You need to pass the connector widget only if the view-model needs any info from it.
