Initializing stuff with store.dispatch

[Pacane]

Hi,

I have this pattern where I initially injected a store instance in all my components using it (I wasn't aware of new StoreProvider.of(...)).

In my App, in some places, I also do 1 time initializations (ie: fetch data via store.dispatch(...)) in initState(). Previously, I could do it fine, because I had an instance of my Store.

Now I tried to move towards to new StoreProvider.of(...), but I faced the issue where context.inheritFromWidgetOfExactType(StoreProvider) can't be called in initState. Is there a way to achieve that somehow?

Seems like the Flutter docs suggest that I use didChangeDependencies() but that is not called only 1 time.

Thanks

Hey hey :)

I can't speak to a custom implementation you've got going, but if you're using the "out of the box" StoreConnector and StoreBuilder Widgets, you can provide an onInit or onDispose function that will be fired when the Widget is first initialized and when it's disposed. Those would probably be my recommended way of initializing / disposing data at the right time.

To fix up your own implementation, the Trick I use: the StoreConnector widget itself doesn't access the Store using context within the initState method, but rather creates a new Widget in the build method where Context is available and passes the Store to that widget. Then the Store is available in the State class as the widget.store property.

Do either of those options work for ya?

The first option did it, thanks!

I wasn't aware of the onInit function.
