Text fields allow users to type text into an app. They are used to build forms, send messages, create search experiences, and more. In this recipe, explore how to create and style text fields.

Flutter provides two text fields: TextField and TextFormField.

TextField

TextField is the most commonly used text input widget.

By default, a Textfield is decorated with an underline. You can add a label, icon, inline hint text, and error text by supplying an InputDecoration as the decoration property of the TextField. To remove the decoration entirely (including the underline and the space reserved for the label), set the decoration to null.

TextField(
  decoration: InputDecoration(
    border: InputBorder.none,
    hintText: 'Enter a search term'
  ),
);

TextFormField

TextFormField wraps a TextField and integrates it with the enclosing Form. This provides additional functionality, such as validation and integration with other FormField widgets.

TextFormField(
  decoration: InputDecoration(
    labelText: 'Enter your username'
  ),
);
