setValue<K extends Object, V> method
Null safety
- BuildContext context,
- K key,
- V value
Changes the app model's value
for key
and rebuilds any widgets
that have created a dependency on key
with SharedAppData.getValue.
If value
is ==
to the current value of key
then nothing
is rebuilt.
The value
is expected to be immutable because intrinsic
changes to the value will not cause dependent widgets to be
rebuilt.
Unlike SharedAppData.getValue, this method does not create a dependency
between context
and key
.
The type parameter K
is the type of the value's keyword and V
is the type of the value.
Implementation
static void setValue<K extends Object, V>(BuildContext context, K key, V value) {
final _SharedAppModel? model = context.getElementForInheritedWidgetOfExactType<_SharedAppModel>()?.widget as _SharedAppModel?;
assert(_debugHasSharedAppData(model, context, 'setValue'));
model!.sharedAppDataState.setValue<K, V>(key, value);
}
