useMemoized<T> function

T useMemoized<T>(ValueGetter<T> valueGetter, { Object? key, })

Caches the instance of a complex object.

During the first build, useMemoized will call valueGetter and return its result. Later, when the HookWidget rebuilds, the call to useMemoized will return the previously created instance.

A subsequent useMemoized call with a different key will re-invoke the function to create a new instance.

Implementation

T useMemoized<T>(ValueGetter<T> valueGetter, {Object? key}) {
  return use(_MemoizedHook<T>.new, key: key, data: valueGetter, debugLabel: 'useMemoized<$T>');
}
