Flutter TextField A TextField or TextBox is an input element which holds the alphanumeric data, such as name, password, address, etc. It is a GUI control element that enables the user to enter text information using a programmable code. It can be of a single-line text field (when only one line of information is required) or multiple-line text field (when more than one line of information is required).

TextField in Flutter is the most commonly used text input widget that allows users to collect inputs from the keyboard into an app. We can use the TextField widget in building forms, sending messages, creating search experiences, and many more. By default, Flutter decorated the TextField with an underline. We can also add several attributes with TextField, such as label, icon, inline hint text, and error text using an InputDecoration as the decoration. If we want to remove the decoration properties entirely, it is required to set the decoration to null.

FlatButton and RaisedButton have been replaced by TextButton and ElevatedButton respectively. ButtonTheme has been replaced by TextButtonTheme and ElevatedButtonTheme. The original classes will eventually be removed, please migrate code that uses them. There's a detailed migration guide for the new button and button theme classes in flutter.dev/go/material-button-migration-guide.

Flutter Text A Text is a widget in Flutter that allows us to display a string of text with a single line in our application. Depending on the layout constraints, we can break the string across multiple lines or might all be displayed on the same line. If we do not specify any styling to the text widget, it will use the closest DefaultTextStyle class style. This class does not have any explicit style. In this article, we are going to learn how to use a Text widget and how to style it in our application.

Here is a simple example to understand this widget. This example shows our project's title in the application bar and a message in the application's body.
