How to shift focus to the next TextField in Flutter? 💡

Are you new to Flutter and building a form with multiple text inputs? 📝 Have you noticed that the keyboard "next" button does not shift the focus to the next field, but instead triggers the "done" action, hiding the keyboard? 🤔

Don't worry, you're not alone! Many Flutter developers have encountered this issue. But fear not, there is a solution! Let's dive into how you can easily shift the focus to the next TextField in Flutter and improve the user experience of your form. 💪

The Issue:

By default, the keyboard "next" button in Flutter's TextFormField widget triggers the "done" action, which hides the keyboard. This behavior can be frustrating for users trying to fill out a form with multiple fields, as they have to manually tap on each field to enter information. 😩

The Solution:

To shift the focus from one TextField to the next when the keyboard "next" button is pressed, we can use the FocusNode class in Flutter. The FocusNode class allows us to control the focus of different widgets within our app. 🎯

Here's how you can implement it:

1. Create a FocusNode instance for each TextField in your form:

FocusNode _firstNameFocusNode = FocusNode();
FocusNode _lastNameFocusNode = FocusNode();

1. Assign the FocusNode instance to each TextFormField widget:

TextFormField(
  focusNode: _firstNameFocusNode,
  // Other properties
)

1. Listen for the keyboard "next" button press and shift the focus to the next field:

TextFormField(
  focusNode: _firstNameFocusNode,
  textInputAction: TextInputAction.next,
  onFieldSubmitted: (value) => _lastNameFocusNode.requestFocus(),
  // Other properties
)

In the example above, when the user presses the "next" button on the keyboard after entering a value in the first name field, the focus will shift to the last name field. This provides a seamless experience for filling out forms. 🌟

It's That Easy! 🎉

Implementing this solution will enhance the user experience of your form by allowing users to seamlessly move from one field to the next using the keyboard "next" button. No more manually tapping on each field! 🙌
