keyboard_detection_tizen 0.1.0

A Tizen-specific Flutter plugin that detects software keyboard (input panel) visibility and state changes.

keyboard_detection_tizen

A Tizen-specific Flutter plugin that detects software keyboard (input panel) visibility and size on Tizen devices. The public API mirrors the keyboard_detection package.

The original keyboard_detection package detects keyboard visibility from MediaQuery.viewInsets.bottom, which is not populated on Tizen. This plugin listens to the tizen/internal/inputpanel event channel exposed by the flutter-tizen embedder instead, and reads the keyboard geometry (height, width, position) from the same channel.

Warning Requires flutter-tizen 3.41.9-tizen.1.0.0 or later. Earlier versions of the embedder do not publish geometry on the tizen/internal/inputpanel channel, so the controller will stay in KeyboardState.unknown.

Usage

dependencies:
  keyboard_detection_tizen: ^0.1.0

import 'package:keyboard_detection_tizen/keyboard_detection_tizen.dart';

final controller = KeyboardDetectionController(
  onChanged: (state) => debugPrint('keyboard: $state'),
);

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Column(
      children: [
        const TextField(),
        StreamBuilder<KeyboardState>(
          stream: controller.stream,
          builder: (_, snapshot) => Text(
            'state: ${snapshot.data ?? KeyboardState.unknown} '
            'size: ${controller.size}',
          ),
        ),
      ],
    ),
  );
}

Limitations

• The Tizen input panel channel emits show / hide / will_show only. KeyboardState.hiding is therefore never reached on Tizen.
• Geometry values are physical pixels reported by ecore_imf. Convert with MediaQueryData.devicePixelRatio if you need logical pixels.
• Floating / split keyboards are not supported.
