flip_panel #

A package for flip panel with built-in animation

How to use #

import 'package:flip_panel/flip_panel.dart';

Create a flip panel from iterable source:

final digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9];

FlipPanel.builder(
    itemBuilder: (context, index) => Container(
       color: Colors.black,
       padding: const EdgeInsets.symmetric(horizontal: 6.0),
       child: Text(
         '${digits[index]}',
         style: TextStyle(
             fontWeight: FontWeight.bold,
             fontSize: 50.0,
             color: Colors.white),
       ),
     ),
    itemsCount: digits.length,
    period: const Duration(milliseconds: 1000),
    loop: 1,
)

Create a flip panel from stream:

FlipPanel<int>.stream(
      itemStream: Stream.periodic(Duration(milliseconds: 1000), (count) => count % 10),
      itemBuilder: (context, value) => Container(
        color: Colors.black,
        padding: const EdgeInsets.symmetric(horizontal: 6.0),
        child: Text(
          '$value',
          style: TextStyle(
            fontWeight: FontWeight.bold,
            fontSize: 50.0,
            color: Colors.white
          ),
        ),
      ),
      initValue: 0,
  );
