多个小部件使用相同的GlobalKey

您可以手动创建密钥并使用静态/常量值吗？例如…

import 'package:flutter/widgets.dart';class RIKeys {  static final riKey1 = const Key('__RIKEY1__');  static final riKey2 = const Key('__RIKEY2__');  static final riKey3 = const Key('__RIKEY3__');}

然后在…

    body: new TabBarView( children: [   new RefreshIndicator(new RefreshIndicator(// Use the Manual Static Value instead ...     key: RIKeys.riKey1,     onRefresh: _actualizoData,     child: new ListView.builder(         padding: new EdgeInsets.only(top: 5.0),         itemCount: linea_reservas.length * 2,         itemBuilder: (BuildContext context, int position) {if (position.isOdd) return new Divider();final index = position ~/ 2;return _buildRow(index);         }),   ),

我在类似情况下取得了一些成功……尤其是在redux或其他类似模式下……
