of<T> method

T of <T>(
  1. BuildContext context,
  2. {bool listen: true}

Obtains the nearest Provider<T> up its widget tree and returns its value.

If listen is true, later value changes will trigger a new State.build to widgets, and State.didChangeDependencies for StatefulWidget.

listen: false is necessary to be able to call Provider.of inside State.initState or the create method of providers like so:

  create: (context) {
    return Model(Provider.of<Something>(context, listen: false)),


static T of<T>(BuildContext context, {bool listen = true}) {
  assert(context != null);
    context.owner.debugBuilding ||
        listen == false ||
Tried to listen to a value exposed with provider, from outside of the widget tree.

This is likely caused by an event handler (like a button's onPressed) that called
Provider.of without passing `listen: false`.

To fix, write:
Provider.of<$T>(context, listen: false);

It is unsupported because may pointlessly rebuild the widget associated to the
event handler, when the widget tree doesn't care about the value.

The context used was: $context

  final inheritedElement = _inheritedElementOf<T>(context);

  if (listen) {

  return inheritedElement.value;
