how to implement a change font size in flutter code example
Example: flutter change android default font size
/// Android has different 'textscalefactor' settings, like:
/// 'Small: 0.85', 'Default: 1.0', 'Large: 1.15', 'Largest: 1.3'
/// To make sure the text in your app stays as you intended it to,
/// use the MediaQuery Widget to overwrite the system default:
Widget build(BuildContext context) {
return MediaQuery(
data: MediaQuery.of(context).copyWith(textScaleFactor: 1.15), // Large
child: Scaffold(),
),
};
