Walkthrough

The notification components now have TypeScript implementations with Flow compatibility. They define typed constants and public exports, support localized dismissal and icon variants, render notifications through an accessible portal, and update tests and Storybook stories.

Changes

Notification component migration

Layer / File(s)	Summary
Notification contract and behavior src/components/notification/constants.*, src/components/notification/Notification.*, src/components/notification/__tests__/Notification.test.tsx	Adds typed notification constants and props. The component supports localized close controls, configurable duration and overflow, icon variants, automatic dismissal, and timer cleanup. Tests cover icon rendering, overflow options, and unmount timer behavior.
Notification portal and focus handling src/components/notification/NotificationsWrapper.*, src/components/notification/__tests__/NotificationsWrapper.test.tsx	Adds typed portal rendering with aria-live="polite" and conditional focus trapping. Tests verify the portal, focus trap, and notification counts.
Public exports and Storybook wiring src/components/notification/index.*, src/components/notification/stories/*	Exports components, constants, and prop types. Updates Storybook state and helper parameters with TypeScript annotations.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Poem

I’m a rabbit with typed little ears,
Sorting alerts through portals and gears.
Timers hop clear, icons shine bright,
Close buttons speak softly and right.
The notification burrow is neat—
TypeScript makes every hop complete!

Inline comments:
In `@src/components/notification/__tests__/NotificationsWrapper.test.tsx`:
- Line 12: Update the assertion in the NotificationsWrapper test to inspect the
rendered Portal’s aria-live prop and verify it equals “polite”, replacing the
ineffective wrapper.props() truthiness check.

In `@src/components/notification/Notification.tsx`:
- Around line 56-75: Separate the internal Notification props used by injectIntl
from the exported public props so consumers are not required to provide intl.
Keep intl available to the wrapped Notification implementation, while exporting
a type based on the remaining consumer-facing props and preserving the existing
children, className, duration, and onClose contract.
