themes, styles, and media
you can style flutter apps with little effort.
styling includes switching between light and dark themes,
changing the design of your text and UI components,
and more. this section covers how to style your apps.

using dark mode
in SwiftUI, you call the preferredColorScheme()
function on a view to use dark mode.
in flutter, you can control light and dark mode at the app-level.
to control the brightness mode, use the theme property
of the app class:
<code_start>
CupertinoApp(
theme: CupertinoThemeData(
brightness: brightness.dark,
),
home: HomePage(),
);

styling text
in SwiftUI, you use modifier functions to style text.
for example, to change the font of a text string,
use the font() modifier:
to style text in flutter, add a TextStyle widget as the value
of the style parameter of the text widget.
<code_start>
text(
'hello, world!',
style: TextStyle(
fontSize: 30,
fontWeight: FontWeight.bold,
color: CupertinoColors.systemYellow,
),
),
<code_end>

styling buttons
in SwiftUI, you use modifier functions to style buttons.
to style button widgets in flutter, set the style of its child,
or modify properties on the button itself.
in the following example:
<code_start>
child: CupertinoButton(
color: CupertinoColors.systemYellow,
onPressed: () {},
padding: const EdgeInsets.all(16),
child: const text(
'do something',
style: TextStyle(
color: CupertinoColors.systemBlue,
fontSize: 30,
fontWeight: FontWeight.bold,
),
),
),

using custom fonts
in SwiftUI, you can use a custom font in your app in two steps.
first, add the font file to your SwiftUI project. after adding the file,
use the .font() modifier to apply it to your UI components.
in flutter, you control your resources with a file
named pubspec.yaml. this file is platform agnostic.
to add a custom font to your project, follow these steps:
add your custom font(s) under the fonts section.
after you add the font to your project, you can use it as in the
following example:
<code_start>
text(
'cupertino',
style: TextStyle(
fontSize: 40,
fontFamily: 'bungeespice',
),
)
<code_end>
