긴급) appBar 색상 이슈

[Cheol]

-- main.dart --

import 'package:flutter/material.dart';
import 'package:instagram/style.dart';
import 'style.dart' as style;

void main() {
  runApp(
      MaterialApp(
          theme: style.theme,
          home: MyApp())
  );
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
            title: Text("Instagram", style: TextStyle(fontSize: 20),),
            actions: [
              IconButton(
                icon: Icon(Icons.add_box_outlined),
                iconSize: 30,
                onPressed: () {},
              )
            ],
      ),

      body: Text('Hello Would'),

bottomNavigationBar: BottomNavigationBar(
        showSelectedLabels: false,
        showUnselectedLabels: false,
        items: [
          BottomNavigationBarItem(icon: Icon(Icons.home_outlined), label: '홈'),
          BottomNavigationBarItem(icon: Icon(Icons.shopping_bag_outlined), label: '샵')
        ],
      ),
    );
  }
}

-- style.dart --

import 'package:flutter/material.dart';

var theme = ThemeData(

  textButtonTheme: TextButtonThemeData(
    style: TextButton.styleFrom(
      backgroundColor: Colors.grey,
    )
  ),

  iconTheme: IconThemeData(
    color: Colors.blue,
  ),

  appBarTheme: AppBarTheme(
    backgroundColor: Colors.white,
    titleTextStyle: TextStyle(color: Colors.black),
    actionsIconTheme: IconThemeData(color: Colors.black),
    elevation: 1.0,
    shadowColor: Colors.black.withOpacity(0.5),
  ),

  textTheme: TextTheme(),
);

플러터 강의 보며 잘 따라하고 있는데  앱바의 색상이 심상치 않습니다.
elevation: 1.0, 이걸 적용하자마자 탁한 색으로 바뀌는데 이거 해결 못하나요
배경색이 white가 아니여도 전부 조금씩 탁해집니다..

surfaceTintColor 조절해봅시다
