AppText class

A customizable text widget.

The AppText widget provides an extended Text widget that allows customization of text styles based on predefined typography categories (e.g., display, headline, title, body, and label) and sizes (large, medium, and small). This makes it easier to maintain a consistent text appearance throughout the application.

Each category and size combination has a dedicated constructor, such as AppText.displayLarge, AppText.headlineMedium, AppText.titleSmall, and so on.

The color, height, fontSize, fontWeight, and letterSpacing arguments are optional and can be used to further customize the text style.

The textAlign, maxLines, and overflow arguments are inherited from the Text widget and have the same behavior.

Example usage:

dart /// AppText.headlineLarge( /// 'This is a large headline', /// color: Colors.blue, /// letterSpacing: 1.2, /// ), /// /// See also:

  • Text, which is the base widget for displaying text.
  • TextStyle, which holds the style properties for the text.
  • Theme, which holds the text theme used for styling the text.

getter/setter pair
color → Color?
The color of the text.
final
data → String?
The text to display.
finalinherited
fontSize → double?
fontSize: The size of the text font.
final

final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
letterSpacing → double?
The amount of space between the letters of the text.
final
locale → Locale?
Used to select a font when the same Unicode character can be rendered differently, depending on the locale.
finalinherited
