Flutter Icon Size

Flutter Icon Size

To set specific size for an Icon widget, set size property with a double value, where the double value represents the number of logical pixels.

Syntax

Icon(
  Icons.account_balance,
  size: 50.0,
),

Example

Flutter Application with three Icon widgets, each with different size.

main.dart

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

/// main application widget
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Application';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const MyStatelessWidget(),
      ),
    );
  }
}

/// stateless widget that the main application instantiates
class MyStatelessWidget extends StatelessWidget {
  const MyStatelessWidget({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Column(
      crossAxisAlignment: CrossAxisAlignment.stretch,
      children: const <Widget>[
        Icon(
          Icons.account_balance,
          size: 50.0,
        ),
        Icon(
          Icons.account_balance,
          size: 100.0,
        ),
        Icon(
          Icons.account_balance,
          size: 200.0,
        ),
      ],
    );
  }
}
