FontFeature.scientificInferiors constructor Null safety

const FontFeature.scientificInferiors()

Use scientific inferiors. (sinf)

Some fonts have variants of the figures (e.g. the digit 2) that, when this feature is enabled, render in a manner more appropriate for subscripted digits ("inferiors") used in scientific contexts, e.g. the subscripts in chemical formulae.

This may override other features that substitute glyphs.

The Piazzolla font supports the sinf feature. It causes digits to be smaller and subscripted.

import 'dart:ui';

import 'package:flutter/widgets.dart';

void main() => runApp(const ExampleApp());

class ExampleApp extends StatelessWidget {
  const ExampleApp({super.key});

  @override

      builder: (BuildContext context, Widget? navigator) =>
          const ExampleWidget(),
      color: const Color(0xffffffff),
    );
  }
}

class ExampleWidget extends StatelessWidget {
  const ExampleWidget({super.key});

  @override
  Widget build(BuildContext context) {
    // The Piazzolla font can be downloaded from Google Fonts (https://www.google.com/fonts).
    return const Text(
      'C8H10N4O2',
