keyboard_visibility 套件是一個 Flutter 插件，讓開發者能夠偵測 Android 與 iOS 裝置上軟鍵盤的可見狀態。它提供簡單的 API 來監聽鍵盤顯示/隱藏事件，讓應用程式能動態回應——例如調整版面或滾動內容進入視圖。這在表單或聊天介面中特別實用，因為使用者輸入需要視覺反饋。此套件跨平台無縫運作，設定簡單，非常適合響應式 UI。

Notification service for soft-keyboard visibility
Add the dependency to your pubspec.yaml file in the root folder of your project. Look for the 'dependencies:'-line and add the following line after this line:
keyboard_visibility: any
or
keyboard_visibility: ^[CURRENT VERSION NUMBER]
(Please note that the two spaces in the beginning of the line are important) Run 'flutter packages get' in your root folder after saving the pubspec.yaml file. For additional documentation about the pubspec.yaml file please refer to the official flutter documentation using packages
Import package:keyboard_visibility/keyboard_visibility.dart, instantiate KeyboardVisibilityNotification
and use the Android and iOS notifications to get events about changes of the visibility of the soft-keyboard
The best practice to call the addNewListener function is inside the initState function as in the following example:
import 'package:keyboard_visibility/keyboard_visibility.dart';
@protected
void initState() {
super.initState();
KeyboardVisibilityNotification().addNewListener(
onChange: (bool visible) {
print(visible);
},
);
}
