2. Implement a rounded shape button:

In the Dart file where you want to implement the rounded shape button, import the necessary packages:

Copy Code


import 'package:flutter/material.dart';

Inside the build method of your widget, use the ElevatedButton widget to create the button with a rounded shape:

Copy Code


ElevatedButton(
  onPressed: () {
    // Add your button click logic here
  },
  child: Text(
    'Click Me',
    style: TextStyle(
      fontSize: 16,
    ),
  ),
  style: ElevatedButton.styleFrom(
    shape: RoundedRectangleBorder(
      borderRadius: BorderRadius.circular(20), // Adjust the radius to change the button's roundness
    ),
    padding: EdgeInsets.symmetric(horizontal: 20, vertical: 10), // Adjust the padding for the button's size
    primary: Colors.blue, // Set the background color of the button
  ),
)

You can adjust the borderRadius property to change the roundness of the button. Use the padding property to adjust the button’s size by specifying horizontal and vertical padding values. Modify the primary property to set the background color of the button.

3. Use the rounded shape button in your app:

In the Dart file where you want to use the rounded shape button, import the necessary packages and add the button widget to your widget tree.

Copy Code


import 'package:flutter/material.dart';

class MyScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: ElevatedButton(
          onPressed: () {
            // Add your button click logic here
          },
          child: Text(
            'Click Me',
            style: TextStyle(
              fontSize: 16,
            ),
          ),
          style: ElevatedButton.styleFrom(
            shape: RoundedRectangleBorder(
              borderRadius: BorderRadius.circular(20),
            ),
            padding: EdgeInsets.symmetric(horizontal: 20, vertical: 10),
            primary: Colors.blue,
          ),
        ),
      ),
    );
  }
}

4. Test the rounded shape button:

Save your changes and run the app using the following command in your terminal:

Copy Code


flutter run

5. Observe the rounded shape button in action:

Upon running the app, you will see the rounded shape button with the specified roundness, size, and color. The button will provide a visually appealing and modern look to your Flutter app’s UI.

Sample Code:

Copy Code


 import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Custom Tab Bar Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Custom Tab Bar Example'),
      ),
      body: Center(
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.  start,
          mainAxisAlignment: MainAxisAlignment. start,
          children:   [
          SizedBox(height: 100,),
        ElevatedButton(

  onPressed: () {
    // Button action
  },
  style: ElevatedButton.styleFrom(  
  
 padding: EdgeInsets.symmetric(horizontal: 40,vertical: 20),
    backgroundColor:   Colors.   black,
    textStyle:    TextStyle(  color: Colors.  white),
    shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(20), // Adjust the border radius as needed
    ),
  ),
  child: Text('Button'),
),
SizedBox(height: 20,),
TextButton(
  onPressed: () {
    // Button action
  },
  style: TextButton.styleFrom(
    padding: EdgeInsets.symmetric(horizontal: 40,vertical: 20),
     
    textStyle:    TextStyle(  color: Colors.  white),
    elevation: 1.1,
    shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(30), // Adjust the border radius as needed
    ),
  ),
  child: Text('Button'),
),



          ],
        ),
      )  );
  }
}
