Typography class Null safety
The color and geometry TextThemes for Material apps.
The text theme provided by the overall Theme, ThemeData.textTheme, is based on the current locale's MaterialLocalizations.scriptCategory and is created by merging a color text theme - black for Brightness.light themes and white for Brightness.dark themes - and a geometry text theme, one of englishLike, dense, or tall, depending on the locale.
To lookup the localized text theme use
Theme.of(context).textTheme.
The color text themes are blackMountainView, whiteMountainView, blackCupertino, and whiteCupertino. The Mountain View theme TextStyles are based on the Roboto fonts as used on Android. The Cupertino themes are based on the San Francisco font fonts as used by Apple on iOS.
Two sets of geometry themes are provided: 2014 and 2018. The 2014 themes correspond to the original version of the Material Design spec and are the defaults. The 2018 themes correspond the second iteration of the specification and feature different font sizes, font weights, and letter spacing values.
By default, ThemeData.typography is Typography.material2014(platform: platform) which uses englishLike2014, dense2014 and tall2014. To use
the 2018 text theme geometries, specify a value using the material2018
constructor:
typography: Typography.material2018(platform: platform)
