Answer 1

you can create this UI like this

  import 'package:flutter/material.dart';

  class Home extends StatefulWidget {
    const Home({super.key});

    @override
    State<Home> createState() => _HomeState();
  }

  class _HomeState extends State<Home> {
    List imagesList = [//your images list];
    @override
    Widget build(BuildContext context) {
      return Scaffold(
        appBar: AppBar(),
        body: Center(
          child: Container(
            child: Row(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                Row(
                  mainAxisAlignment: MainAxisAlignment.center,
                  children: [
                    for (int i = 0; i < imagesList.length; i++)
                      Container(
                        margin: EdgeInsets.symmetric(vertical: 0),
                        child: Align(
                            widthFactor: 0.5,
                            child: CircleAvatar(
                              radius: 50,
                              backgroundColor: Colors.white,
                              child: CircleAvatar(
                                radius: 40,
                                backgroundImage: NetworkImage(
                                  imagesList[i],
                                ),
                              ),
                            )),
                      )
                  ],
                ),
                SizedBox(
                  width: 20,
                ),
                CircleAvatar(
                  
                  backgroundColor: Colors.grey.shade200,
                  radius: 40,
                  child: Center(child: Icon(Icons.add)),
                ),
