FontFeature.slashedZero constructor Null safety

const FontFeature.slashedZero()

Use the slashed zero. (zero)

Some fonts contain both a circular zero and a zero with a slash. This enables the use of the latter form.

This is overridden by FontFeature.oldstyleFigures.

The Source Code Pro font supports the zero feature. It causes the zero digit to be drawn with a slash rather than the default rendering, which in this case has a dot through the zero rather than a slash.

To create a local project with this code sample, run:
flutter create --sample=dart.dart_ui.FontFeature.slashedZero.1 mysample 
import 'dart:ui';

import 'package:flutter/widgets.dart';

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

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

  @override
  Widget build(BuildContext context) {
    return WidgetsApp(
      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 Source Code Pro font can be downloaded from Google Fonts (https://www.google.com/fonts).
    return const Text(
      'One million is: 1,000,000.00',
      style: TextStyle(
        fontFamily: 'Source Code Pro',
        fontFeatures: <FontFeature>[
          FontFeature.slashedZero(),
        ],
      ),
    );
  }
}
