Chain style programming syntax sugar utilities for Flutter widgets.

Too many child or children parameters with their nestings and indents makes Flutter code hard to read, so here comes this package. This package provides a chain style programming syntax to make your code clean and tidy, especially with so many single child widgets. Talk is cheap, you can read the following code examples to feel it.

How to use

Following codes are equivalent widgets but before and after using such package.

Before:

import 'package:flutter/widgets.dart';

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

  @override
  Widget build(BuildContext context) {
    return MediaQuery(
      data: MediaQueryData.fromView(View.of(context)),
      child: Directionality(
        textDirection: TextDirection.ltr,
        child: ColoredBox(
          color: const Color(0xff804044),
          child: DefaultTextStyle(
            style: DefaultTextStyle.of(context).style.copyWith(
                  color: const Color(0xffdedcda),
                ),
            child: IconTheme(
              data: IconTheme.of(context).copyWith(
                color: const Color(0xffdedcda),
              ),
              child: const Center(
                child: Text('app root'),
              ),
            ),
          ),
        ),
      ),
    );
  }
}

After:

import 'package:flutter/widgets.dart';
import 'package:wrap/wrap.dart';

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

  @override
  Widget build(BuildContext context) => const Text('app root')
      .wrapCenter
      .wrapForeground(context, const Color(0xffdedcda))
      .wrapBackground(const Color(0xff804044))
      .ensureTextEnvironment(context);
}
