Keyboard Height Plugin for Flutter

keyboard_height_plugin is a Flutter plugin for iOS and Android that provides the keyboard size before the keyboard animation occurs for showing or hiding it. This helps eliminate lag when positioning widgets around the keyboard, such as placing a TextField above the keyboard.

Installation

To install keyboard_height_plugin, add it to your pubspec.yaml file under the dependencies section:

dependencies:
  keyboard_height_plugin: ^0.0.4

Usage

To use the keyboard_height_plugin, first import it in your Dart file:

import 'package:keyboard_height_plugin/keyboard_height_plugin.dart';

Next, create a stateful widget and declare a variable to store the keyboard height and create an instance of the KeyboardHeightPlugin:

class _HomePageState extends State<HomePage>; {
  double _keyboardHeight = 0;
  final KeyboardHeightPlugin _keyboardHeightPlugin = KeyboardHeightPlugin();
  // ... rest of code ...
}

Then, initialize the KeyboardHeightPlugin in your initState method and listen for changes in the keyboard height:

@override
void initState() {
  super.initState();
  _keyboardHeightPlugin.onKeyboardHeightChanged((double height) {
    setState(() {
      _keyboardHeight = height;
    });
  });
}

Use the _keyboardHeight variable to position your widgets around the keyboard.
