Flutter -如何给IconButton添加颜色？

IconButton(
  icon: Icon(Icons.home),
  color: Colors.blue,
  onPressed: () {
    // 处理点击事件
  },
)

MaterialApp(
  theme: ThemeData(
    iconTheme: IconThemeData(color: Colors.red),
  ),
);

IconButton(
  icon: Icon(Icons.home),
  color: Colors.blue,
  splashColor: Colors.green,
  onPressed: () {
    // 处理点击事件
  },
)

IconButton(
  icon: Icon(Icons.home),
  color: Colors.blue,
  highlightColor: Colors.purple,
  onPressed: () {
    // 处理点击事件
  },
)

IconButton(
  icon: Icon(Icons.home),
  color: Colors.blue,
  disabledColor: Colors.grey,
  onPressed: null, // 设置为null表示按钮不可点击
)

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('IconButton Color Example'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              IconButton(
                icon: Icon(Icons.home),
                color: Colors.blue,
                splashColor: Colors.green,
                onPressed: () {
                  print('Home button pressed!');
                },
              ),
              SizedBox(height: 20),
              IconButton(
                icon: Icon(Icons.settings),
                color: Colors.red,
                disabledColor: Colors.grey,
                onPressed: null,
              ),
            ],
          ),
        ),
      ),
    );
  }
}
