In this blog, we’ll explore how to show automatically keyboard focus in Flutter for textField.
When a text field is selected and accepting input, it is said to have “focus.”
Generally, users focus on a text field by tapping, and developers shift focus to a text field programmatically using the tools described in this recipe.

class KeyboardFocusDemo extends StatefulWidget { const KeyboardFocusDemo({super.key}); @override State<KeyboardFocusDemo> createState() => _KeyboardFocusDemoState(); } class _KeyboardFocusDemoState extends State<KeyboardFocusDemo> { final FocusNode _nameFocusNode = FocusNode(); final FocusNode _emailFocusNode = FocusNode(); final FocusNode _passFocusNode = FocusNode(); @override void dispose() { _nameFocusNode.dispose(); _emailFocusNode.dispose(); _passFocusNode.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar(), body: Padding( padding: const EdgeInsets.all(8.0), child: Column( children: <Widget>[ TextField( focusNode: _nameFocusNode, decoration: const InputDecoration( labelText: 'Name', border: OutlineInputBorder()), onSubmitted: (value) { _nameFocusNode.unfocus(); FocusScope.of(context).requestFocus(_emailFocusNode); }, ), const SizedBox(height: 16.0), TextField( focusNode: _emailFocusNode, decoration: const InputDecoration( labelText: 'Email', border: OutlineInputBorder()), onSubmitted: (value) { _emailFocusNode.unfocus(); FocusScope.of(context).requestFocus(_passFocusNode); }, ), const SizedBox(height: 16.0), TextField( focusNode: _passFocusNode, decoration: const InputDecoration( labelText: 'Password', border: OutlineInputBorder()), onSubmitted: (value) { _passFocusNode.unfocus(); }, ), ], ), )); } } |
An essential part of the focus system is the “focus node.” An object that represents a widget that can receive focus is called a focus node.
The focus node of a widget becomes active when a user interacts with it by touching it or using the keyboard to navigate to it.
Keyboard Focus in Flutter as the name suggests, manages the focus node. It is the most important and functioning part of Flutter’s.
