我有两个容器，两个容器都有GestureDetector。第一个容器的OnTap工作正常，但不能与另一个容器一起使用。第一个容器是图像，第二个容器是部分在第一个容器上对齐的绿色背景。

new Stack(
            alignment: Alignment(0.0, 1.44),
            children: <Widget>[
              GestureDetector(
                onTap: () => _openImage(context),
                child: Container(
                  width: 340.0,
                  foregroundDecoration: new BoxDecoration(
                      color: Color.fromRGBO(155, 85, 250, 0.55)),
                  height: 240.0,
                  child: FadeInImage.assetNetwork(
                    placeholder: 'assets/dimlight.png',
                    image: post.imageUrl,
                    fit: BoxFit.cover,
                  ),
                ),
              ),
              new GestureDetector(
                child: new Container(
                  color: Colors.green,
                  child: Row(
                    mainAxisSize: MainAxisSize.max,
                    children: <Widget>[
                      SizedBox(width: 7.0),
                      CircleAvatar(
                        backgroundImage: 
                           new AssetImage("assets/boy.png")
                        radius: 30.0,
                      ),
                      SizedBox(
                        width: 7.0,
                      ),
                      Column(
                        crossAxisAlignment: CrossAxisAlignment.start,
                        children: <Widget>[
                          new SizedBox(
                            height: 20.0,
                          ),
                          Text(
                            post.user.name,
                            style: TextStyle(fontWeight: FontWeight.bold),
                          ), …
