Widget HUD #

Simple use of progress Widget HUD with FutureBuilder:

  1. Default HUD
FutureBuilder<String>(
  future: executeHttpRequest(),
  builder: (context, snapshot) {
    return WidgetHUD(
      builder: (context) => Scaffold(
        appBar: AppBar(
          title: Text('Default HUD'),
        ),
        body: Center(
          child: Text(snapshot.hasData ? snapshot.data : ''),
        ),
      ),
      showHUD: !snapshot.hasData,
    );
  },
);
  1. HUD with Label
FutureBuilder<String>(
  future: executeHttpRequest(),
  builder: (context, snapshot) {
    return WidgetHUD(
      hud: HUD(label: 'Executing Http Request'),
      builder: (context) => Scaffold(
        appBar: AppBar(
          title: Text('HUD with Label'),
        ),
        body: Center(
          child: Text(snapshot.hasData ? snapshot.data : ''),
        ),
      ),
      showHUD: !snapshot.hasData,
    );
  },
);
  1. HUD with Label and Detail Label
FutureBuilder<String>(
  future: executeHttpRequest(),
  builder: (context, snapshot) {
    return WidgetHUD(
      hud: HUD(
        label: 'Executing Http Request', 
        detailLabel: 'Please Wait a Moment',
      ),
      builder: (context) => Scaffold(
        appBar: AppBar(
          title: Text('HUD with Label and Detail'),
        ),
        body: Center(
          child: Text(snapshot.hasData ? snapshot.data : ''),
        ),
      ),
      showHUD: !snapshot.hasData,
    );
  },
);

Displaying progress HUD using ModalRoute :

String resultPrimes1;
String resultPrimes2;
String resultPrimes3;

_reload() async {
  setState(() {
    resultPrimes1 = null;
    resultPrimes2 = null;
    resultPrimes3 = null;
  });
  final popup = PopupHUD(
    context,
    hud: HUD(
      label: 'Generating Primes',
      detailLabel: 'Initializing...',
    ),
  );

  popup.show();
  await Future.delayed(Duration(seconds: 2));
  final primes1 = primesMap().take(10).join(', ');

  popup.setDetailLabel('Progress 33%...');
  await Future.delayed(Duration(seconds: 2));
  final primes2 = primesMap().take(20).skip(10).join(', ');

  popup.setDetailLabel('Progress 66%...');
  await Future.delayed(Duration(seconds: 2));
  final primes3 = primesMap().take(30).skip(20).join(', ');

  popup.setDetailLabel('Done 100%...');
  await Future.delayed(Duration(milliseconds: 500));

  popup.dismiss();
  if (mounted) {
    setState(() {
      resultPrimes1 = primes1;
      resultPrimes2 = primes2;
      resultPrimes3 = primes3;
    });
  }
}

@override
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text(HUDUsingPopup.title),
    ),
    body: Center(
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: <Widget>[
          if (resultPrimes1 != null)
            Text(
              'The first 10 primes :',
              textAlign: TextAlign.center,
              style: Theme.of(context).textTheme.title,
            ),
          if (resultPrimes1 != null)
            Text(
              resultPrimes1,
              textAlign: TextAlign.center,
              style: Theme.of(context).textTheme.subtitle,
            ),
          if (resultPrimes2 != null)
            Text(
              'The second 10 primes :',
              textAlign: TextAlign.center,
              style: Theme.of(context).textTheme.title,
            ),
          if (resultPrimes2 != null)
            Text(
              resultPrimes2,
              textAlign: TextAlign.center,
              style: Theme.of(context).textTheme.subtitle,
            ),
          if (resultPrimes3 != null)
            Text(
              'The third 10 primes :',
              textAlign: TextAlign.center,
              style: Theme.of(context).textTheme.title,
            ),
          if (resultPrimes3 != null)
            Text(
              resultPrimes3,
              textAlign: TextAlign.center,
              style: Theme.of(context).textTheme.subtitle,
            ),
        ],
      ),
    ),
    floatingActionButton: FloatingActionButton(
      child: Icon(Icons.refresh),
      onPressed: _reload,
    ),
  );
}

How about adding some progress to it?

final popup = PopupHUD(
  context,
  hud: HUD(
    label: 'Generating Primes',
    detailLabel: 'Initializing..',
  ),
);

popup.show();
final number = await getPrimes(delayedSeconds: 1);
for (int i = 1; i <= 10; i++) {
  await Future.delayed(Duration(milliseconds: 500));
  final value = i * 0.10;
  popup.setValue(value);
  popup.setDetailLabel('Progress ${(value * 100).toInt()}%..');
}

await Future.delayed(Duration(milliseconds: 500));
popup.dismiss();
