Add TextInput widget for text entry support - #12
Merged
Merged
Conversation
Extends the declarative UI framework with a TextInput widget that follows a controlled-component pattern (Haskell owns the state). The widget takes a placeholder hint, current value, and onChange callback. Changes across the full stack: - Widget ADT: new TextInput constructor - UIBridge.h/hs: UI_NODE_TEXT_INPUT, UI_PROP_HINT, UI_EVENT_TEXT_CHANGE - Render.hs: separate text callback registry, dispatchTextEvent - HaskellMobile.hs: haskellOnUITextChange FFI export (no re-render to avoid EditText cursor flicker) - Android JNI/Java: EditText creation, setHint, TextWatcher integration - 5 new tests covering text callbacks, ID space sharing, and reset Prompt: Implement TextInput widget for haskell-mobile as Phase 1 of gym PR tracker app Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Adds visibility: public to haskell-mobile-lifecycle and haskell-mobile-ui sub-libraries, allowing external packages (like prrrrrrrrr) to depend on them directly for Backpack instantiation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
