Published October 18, 2021

In this flutter Text Input tutorial we will cover how to add place holder text in TextInput. Placeholder text is a text which will inform the user about the type of TextInput. To add placeholder text to textInput field we will use hintText property.

TextField(
  decoration: InputDecoration(
      hintText: 'Enter your FirstName'
  ),
  controller: myControllerFName,
),

In the above code we added PlaceHolder text for user FirstName by using hintText: 'Enter your FirstName'

Let's create simple example to add PlaceHolder Text to TextInput Field

import 'package:flutter/material.dart';

void main() {
  runApp(TextInputPlaceholderExample());
}

class TextInputPlaceholderExample extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Input Placeholder Example',
      home: MyInputPlaceholder(),
    );
  }
}

// Define a custom Form widget.
class MyInputPlaceholder extends StatefulWidget {
  @override
  _MyInputPlaceholderState createState() => _MyInputPlaceholderState();
}

// Define a corresponding State class.
// This class holds the data related to the Form.
class _MyInputPlaceholderState extends State<MyInputPlaceholder> {
  // Create a text controller and use it to retrieve the current value
  // of the TextField.
  final myControllerFName = TextEditingController();
  final myControllerLName = TextEditingController();

  @override
  void dispose() {
    // Clean up the controller when the widget is disposed.
    myControllerFName.dispose();
    myControllerLName.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Text Input Placeholder Tutorial'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Center(child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            TextField(
              decoration: InputDecoration(
                  hintText: 'Enter your FirstName'
              ),
              controller: myControllerFName,
            ),
            SizedBox(height: 10,),
            TextField(
              decoration: InputDecoration(
                  hintText: 'Enter your LastName'
              ),
              controller: myControllerLName,
            ),
          ],
        ),
        ),
      ),
