utopia_hooks
Basic and complex hooks (including SubmitState, ComputedState and supporting widgets).
Highlights
ComputedState
Designed for cases where global/local state is asynchronously fetched, possibly based on some input data. Provides error
handling, cancellation, previous value memoization, deduplication, manual updates and more. Also, via
its useAutoComputedState variant, supports automatic re-fetching (keys), debouncing (debounceDuration) and
conditional computation (shouldCompute).
ComputedWrapper widget family
Convenience widgets for consuming ComputedStates in UI. Has variants for refreshable and non-refreshable states with
simple or list-based values
SubmitState
Designed for cases where user action triggers some asynchronous operation. Supports two usage modes: first, bare-bones
and flexible (submitState.run(operation)) and second, opinionated and convenient (submitState.runSimple(...)).
Supports parallel submits, error handling, retrying and more.
HookStateProviderWidget
Combination of HookWidget and Provider, designed for hook-based global states. Can be used with MultiProvider.
useSimpleEffect
Similar to useEffect, but executes outside the build phase, which fixes common setState-during-build bugs.
useValueWrapper
Simple hook that helps combat memoization issues. Basically a useRef which updates its value on every rebuild. Use in
hooks that take functional arguments.
See useAppLifecycleStateCallbacks for an example.
