Multiple widgets used the same GlobalKey

Could you create your keys “by hand” and use static/constant values? e.g. …

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__');

then in …

    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);

I have done this in a similar situation with some success … especially with redux or other similar patterns …
