Getting started #
Wrap your app in ProviderScope widget:
void main() {
runApp(
ProviderScope(child: App())
);
}
copied to clipboard
Read your providers with of extension method:
GestureDetector(
onTap: () => myProvider.of(context).doSomething()
child: ...
);
copied to clipboard
Each ProviderScope introduces new ProviderContainer, which becomes child of the previous container.
When ProviderScope widget disposes, it disposes ProviderContainer with it.
Overriding and scoping #
It's possible to override provider with another one:
ProviderScope(
overrides: [
myProvider.overrideWith(anotherProvider),
],
child: ...
)
copied to clipboard
Or just scope it:
ProviderScope(
overrides: [
myProvider.scope(),
],
child: ...
)
copied to clipboard
Pass parent #
ProviderScope takes its parent from the BuildContext. But you could override it with parent constructor parameter.
It could be useful with dialogs:
ProviderScope(
overrides: [myVmProvider.scoped()],
child: Builder(
builder: (context) => GestureDetector(
onTap: () {
final container = UncontrolledProviderScope.of(context);
showAlertDialog(
builder: (context) => ProviderScope(
parent: container,
child: ...
)
)
},
child: ...
)
)
)
copied to clipboard
Now your dialog will receive all scoped providers from the parent screen.
