Flutter - How does MultiProvider work with providers of the same type?

Question

For example, I am trying to obtain data emitted for multiple streams at once, but 2 or more of these streams emit data of the same type, lets say a string.

My question i

Answer 1

MultiProvider or not doesn't change anything. If two providers share the same type, the deepest one overrides the value.

It's not possible to obtain the value from a provider that is not the closest ancestor for a given type.

If you need to access all of these values independently, each should have a unique type.

For example, instead of:

Provider<int>(
  value: 42,
  child: Provider<int>(
    value: 84,
    child: <something>
  ),
)

You can do:

class Root {
  Root(this.value);

  final int value;
}

class Leaf {
  Leaf(this.value);

  final int value;
}


Provider<Root>(
  value: Root(42),
  child: Provider<Leaf>(
    value: Leaf(84),
    child: <something>
  ),
)

This allows to obtain each value independently using:

Provider.of<Root>(context)
Provider.of<Leaf>(context);
