keyboard_visibility #

Notification service for soft-keyboard visibility

Usage #

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


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';

void initState() {

    onChange: (bool visible) {
