What is Flutter Text’s Default Font Size?

There are a lot of different design choices that go into creating an app. One of the most important – but often overlooked – is the font size and type. Different fonts can communicate different things to your users, so it’s important to choose the right one.

The default font size for a Flutter app is 14 logical pixels. This is a good size to use because it is large enough that it is easily readable, but not so large that it takes up too much space on the screen.

Following are a few ways to define the font size:

MaterialApp(
  theme: ThemeData(
    textTheme: const TextTheme(
      bodyText1: TextStyle(fontSize: 18.0),
      bodyText2: TextStyle(fontSize: 20.0),
      button: TextStyle(fontSize: 16.0),
    ),
  ),
  home: Scaffold(
    body: Center(child: Text("Font size is 18")),
  ),
)

Text(
	'Apply font size for individual Text widget',
	style: TextStyle(fontSize: 18),
)
