flutter_state_view

flutter state view with loading，empty，error show

使用方法：

    StateView(
      state: state,
      loadingLabel:'加载中...',
      emptyLabel: '空空如也',
      errorLabel: '我错了',
      onRetry: this.onRetry,
      child: Text('成功页面！'),
    ),

快捷使用方法：
//初始化

StateView page;

page = Column(
  mainAxisAlignment: MainAxisAlignment.center, children: <Widget>[
  Text(
    'You have pushed the button this many times11:',
  ),
  Text(
    '$_counter',
    style: Theme.of(context).textTheme.headline4,
  ),
],
).center().pageState();

//改变状态：

page.pageStateLoading("加载中...");
Future.delayed(Duration(seconds: 3)).then((value) {
  page.configErrorImage('imgs/empty.png');
  page.pageStateErrorWithRetry("出错了！",(iserror)=>{
    this._incrementCounter()
  });
}); 

效果图如下：
