You Can use flutter badge plugin and firestore for remove badge when click

Some example code:-

bool _showbadge = false;
.
.
.
.
if(int.parse(snapshot1.data["chat_count"]) > 0){
                    _showbadge = true;
                  }else{
                    _showbadge = false;
                  }

Badge(
      showBadge: _showbadge,
      position: BadgePosition.topEnd(top: 0.55, end: 0.155),
      animationType: BadgeAnimationType.scale,
      badgeContent: Text("${snapshot1.data["chat_count"]}"),
