Summary: This change adds TypeScript/Flow types and RNTester examples for the `selection` data in `TextInput.onChange` event. This is the JS companion to the native changes that add selection data to the onChange event. NOTE:selection only represents the cursor location when returned via onChange as this will not be invoked on a pure selection change without text change. We should also add this note to the documentation. ## Why On the web, text input elements provide `selectionStart` and `selectionEnd` properties that are always accessible during input events. This change exposes the selection data that native now provides, allowing developers to access cursor position during onChange. ## What Changed 1. **Flow Types**: Added optional `selection?: Selection` to `TextInputChangeEventData` 2. **TypeScript Types**: Updated `ReactNativeApi.d.ts` with selection type 3. **RNTester**: Updated examples to display selection in event logs Changelog: [General][Added] - TextInput onChange event types now include optional selection data Reviewed By: cipolleschi, necolas Differential Revision: D90123294

…7249) Summary: The native `TextInput.onChange` event now emits `selection` data (cursor location) on both iOS and Android, added in [162627a](162627a) (#55044). - #55044 The JS companion PR [c1f5445](c1f5445) (#55043) added the corresponding types, but only to two of the three TypeScript/Flow type sources: - #55043 | Type source | Has `selection`? | |---|---| | `TextInput.flow.js` (Flow) | ✅ | | `ReactNativeApi.d.ts` (generated API surface) | ✅ | | `TextInput.d.ts` (legacy public `.d.ts`) | ❌ | The hand-written legacy `TextInput.d.ts` was missed, so consumers relying on it can't access `selection` from the `onChange` event even though native genuinely sends it. This PR adds the optional `selection` field there so all three type sources agree. ## Changelog: [GENERAL] [ADDED] - Add `selection` to `TextInputChangeEventData` in TypeScript types Pull Request resolved: #57249 Test Plan: Type-only change. `selection` is now available and correctly typed on the `onChange` event: ```tsx <TextInput onChange={e => { // e.nativeEvent.selection is now typed as { start: number; end: number } | undefined console.log(e.nativeEvent.selection?.start, e.nativeEvent.selection?.end); }} /> Reviewed By: christophpurrer Differential Revision: D109435915 Pulled By: fabriziocucci fbshipit-source-id: b334e52e0e39a7f9053bf41e93077be90b3d9adf
