Flutter how to display datepicker when textformfield is clicked

In Flutter, you can open a date picker when a TextFormField is clicked. This can be achieved by overriding the onTap event of the TextFormField and then opening a date picker dialog. The showDatePicker method in Flutter displays a date picker dialog, allowing users to select a date. When the user selects a date, you can set that date as the value of the TextFormField.

Here's an example demonstrating how to open a date picker when a TextFormField is clicked:

import 'package:flutter/material.dart'; import 'package:intl/intl.dart'; // Required for formatting date void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Date Picker Example', home: Scaffold( appBar: AppBar( title: Text('Date Picker Example'), ), body: DatePickerTextField(), ), ); } } class DatePickerTextField extends StatefulWidget { @override _DatePickerTextFieldState createState() => _DatePickerTextFieldState(); } class _DatePickerTextFieldState extends State<DatePickerTextField> { final TextEditingController _dateController = TextEditingController(); final DateFormat _dateFormat = DateFormat('yyyy-MM-dd'); // Format for date @override Widget build(BuildContext context) { return Padding( padding: EdgeInsets.all(16.0), child: Column( mainAxisAlignment: MainAxisAlignment.center, children: [ TextFormField( controller: _dateController, readOnly: true, // Make it read-only so users can't type in it decoration: InputDecoration( labelText: 'Select a date', suffixIcon: Icon(Icons.calendar_today), ), onTap: () async { DateTime? selectedDate = await showDatePicker( context: context, initialDate: DateTime.now(), // Default to current date firstDate: DateTime(2000), // Earliest selectable date lastDate: DateTime(2100), // Latest selectable date ); if (selectedDate != null) { // If a date is selected, update the text field with the formatted date _dateController.text = _dateFormat.format(selectedDate); } }, ), ], ), ); } }

Explanation

  • TextFormField with onTap Handler: The onTap handler is used to trigger the date picker when the TextFormField is clicked. The text field is set to read-only (readOnly: true) to prevent manual input.
  • Using showDatePicker: This method shows a date picker dialog. It requires a context, initialDate, firstDate, and lastDate to define the selectable range.
  • Handling the Selected Date: If the user selects a date, it is formatted and set to the TextEditingController, updating the text field's value.
  • Formatting Dates with intl: The intl package is used for formatting dates. It allows you to define how the date is displayed in the text field.

Additional Considerations

  • Customizing Date Picker: You can customize the date picker by specifying additional parameters like locale, textDirection, helpText, etc.
  • Validation: If needed, you can add validation to the TextFormField to ensure a date is selected before proceeding with form submission or other actions.
  • User Experience: Consider adding visual cues, such as a calendar icon, to indicate that clicking on the field opens a date picker.
