Getting Started #

Usage

To use this plugin, add futils as a dependency in your pubspec.yaml file.

dependencies:
  futils: ^0.0.8

In your .dart file.

import 'package:futils/futils.dart';
import 'package:futils/sin_points.dart';
import 'package:futils/loop_banner.dart';
import 'package:futils/fwebview.dart';

Example - FWebView

// receiving message from message channel
FWebView.setMessageChannelCallback((message){
  print('Received message: $message');
  var msg = jsonDecode(message);
  if (msg != null) {
    String url = msg['ShouldOverrideUrl'];
    if (url != null && url.startsWith('fgit:')) {
      FWebView.closeWebView();
      Uri uri = Uri.parse(url);
      String code = uri.queryParameters['code'];
      print('Received github code: $code');
    }
  }
});
FWebView.launchUrlInWebView('https://github.com/login/oauth/authorize?client_id=980af8b605f82ea3f5cc');
FWebView.closeWebView();

Example - SinPoints

MaterialButton(
  onPressed: (){
    setState((){
      _running ^= true;
    });
  },
  child: SizedBox(
    width: 160,
    height: 160,
    child: SinPoints(
      running: _running,
    ),
  ),
)

Example - LoopBanner

Center(
  child: LoopBanner(
    duration: Duration(seconds: 3),
    itemCount: 6,
    itemBuilder: (context, position){
      return Card(
        color: position % 3 == 0 ? Color(0xff33b5e5) :
               position % 3 == 1 ? Color(0xffdd4400) :
                                   Color(0xff44cc00),
        child: MaterialButton(
          onPressed: (){},
          child: Center(
            child: Text('${position + 1}',
              style: TextStyle(
                color: Colors.white,
                fontSize: 40,
              ),
            ),
          ),
        ),
      );
    },
  ),
)
