Flutter- GestureDetector not working with containers in stack

I have two containers in a stack and both containers have GestureDetector.The OnTap for the first container is working fine but it's not working with another container. The first container is the image and the second one is the green background aligned partially over the first container.

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),
                          ),
                          Text(
                            getTimeString(post.timestamp.toString()),
                            style: TextStyle(
                                color: Colors.grey, fontSize: 10.0),
                          ),
                        ],
                      ),
                      SizedBox(
                        width: 20.0,
                      ),
                    ],
                  ),
                ),
                onTap: () => _navigateToDetails(context),
              )
            ],
          )

Try setting the behavior property of GestureDetector to HitTestBehavior.translucent.
