将onPressed函数放在容器上

Question

我需要脱开FlatButton并使用按钮功能的onPressed将这个功能放到所有容器中。我不知道是否有可能...我该怎么做？

Widget _buildFrontWidget() {
    return Container(
        color: Colors.white,
        alignment: Alignment.center,
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text("CARD",
                style: TextStyle(
                    color: Color(0xFF2e282a),
                    fontSize: 20.0,
                    fontWeight: FontWeight.w800)
            ),
            FlatButton(
              onPressed: () => _foldingCellKey?.currentState?.toggleFold(),
              child: Text(
                "Open",
              ),
              textColor: Colors.white,
              color: Colors.indigoAccent,
              splashColor: Colors.white.withOpacity(0.5),
            )
          ],
        ));
  }

  Widget _buildInnerTopWidget() {
    return Container(
        color: Color(0xFFff9234),
        alignment: Alignment.center,
        child: Text("TITLE",
            style: TextStyle(
                color: Color(0xFF2e282a),
                fontFamily: 'OpenSans',
                fontSize: 20.0,
                fontWeight: FontWeight.w800)));
  }

  Widget _buildInnerBottomWidget() {
    return Container(
      color: Color(0xFFecf2f9),
      alignment: Alignment.bottomCenter,
      child: Padding(
        padding: EdgeInsets.only(bottom: 10),
        child: FlatButton(
          onPressed: () => _foldingCellKey?.currentState?.toggleFold(),
          child: Text(
            "Close",
          ),
          textColor: Colors.white,
          color: Colors.indigoAccent,
          splashColor: Colors.white.withOpacity(0.5),
        ),
      ),
    );
  }

像这样包裹在InkWell中

Widget _buildFrontWidget() {
  return InkWell(
    onTap: _foldingCellKey?.currentState?.toggleFold(),
    child: Container(
        color: Colors.white,
        alignment: Alignment.center,
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text("CARD",
                style: TextStyle(
                    color: Color(0xFF2e282a),
                    fontSize: 20.0,
                    fontWeight: FontWeight.w800)),
          ],
        )),
  );
}
