android – Change the location of the text in the flutter

I’m creating my own chat on flutter and I need the time of the last message to be in the upper right corner from the person who wrote photo! But I do not know how to do it, I will be grateful if you help!

child: Column(
                children: [
                  Row(
                    crossAxisAlignment: CrossAxisAlignment.start,
                    children: [
                      ClipRRect(
                          borderRadius: BorderRadius.circular(60),
                          child: Image.asset("images/churka.jpg", height: 60,
                            width: 60,
                            fit: BoxFit.cover,)),
                      SizedBox(width: 10.0,),
                      Column(
                        // mainAxisAlignment: MainAxisAlignment.spaceAround,
                        crossAxisAlignment: CrossAxisAlignment.start,
                        children: [
                          SizedBox(height: 10,),
                          Row(

                            children: [
                              Text('Человек', style: TextStyle(fontSize: 18,
                                  fontWeight: FontWeight.w500),),
                            ],
                          ),
                          Text('Как дела',
                            style: TextStyle(color: Color.fromRGBO(
                                87, 87, 87, 1.0),
                                fontSize: 16,
                                fontWeight: FontWeight.w400),),
                        ],

                      ),
                      Text('11:11', style: TextStyle(color: Color.fromRGBO(
                          87, 87, 87, 1.0),
                          fontSize: 16,
                          fontWeight: FontWeight.w400),),
                    ],
                  ),
                ],
              ),

I tried to put mainAxisAlignment in different ways, but then the position of the name and the last message changes
