Row in Flutter

"row" is a widget that arranges  children in a horizontal row. It is part of the widget system used to create user interfaces in Flutter. You can  create a set of children using the row widget.
These child elements can be various widgets such as text, images, buttons, etc.

Row(
  children: [
   // Widget Here
   // Widget Here
   // Widget Here
  ],
)

Here's a simple example of using the Row widget in Flutter:

import 'package:flutter/material.dart';

void main() {
  runApp(
      MaterialApp(
        home: Scaffold(
          appBar: AppBar(
            title: Text('Row Example'),
          ),
          body: MyApp(),
        ),
      )
  );
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return
      Center(
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,//  you can use spaceAround, center, spaceBetween, spaceEvenly  
          children: [
           Container(
             height: 100,
             width: 100,
             color: Colors.blue,
             alignment: Alignment.center,
             child: Text("Text 1"),
           ),
            Container(
              height: 100,
              width: 100,
              color: Colors.red,
              alignment: Alignment.center,
              child: Text("Text 2"),
            ),
            Container(
              height: 100,
              width: 100,
              color: Colors.amber,
              alignment: Alignment.center,
              child:  Text("Text 3"),
            )
          ],
        )
      );
  }
}

The Row widget is used to create a horizontal arrangement of its children.
The mainAxisAlignment property is set to MainAxisAlignment.spaceEvenly(you can use spaceAround, center, spaceBetween, spaceEvenly ), which means that the children will be spaced evenly in the row.

Open Device Manager, run the emulator, and  then run the application. Next, check the working output and check the output  you declared in your code.
