[Flutter]Setting Status bar color in theme

statusBar를 다크모드에 따라 흰색, 검정색으로 설정하는 방법.

1. appBar에서 brightness로 설정 해주면 된다.

return Scaffold(
      appBar: AppBar(
        brightness: Brightness.light,  //<--Here!!!
        title: Text(widget.title),
      ),

2. 더 상단의 MaterialApp에서 appBarTheme 속성을 이용해 설정한다.

...
MaterialApp(
    themeMode: ThemeMode.light, // Change it as you want
    theme: ThemeData(
        primaryColor: Colors.white,
        primaryColorBrightness: Brightness.light,
        brightness: Brightness.light,
        primaryColorDark: Colors.black,
        canvasColor: Colors.white,
        // next line is important!
        appBarTheme: AppBarTheme(brightness: Brightness.light)),
    darkTheme: ThemeData(
        primaryColor: Colors.black,
        primaryColorBrightness: Brightness.dark,
        primaryColorLight: Colors.black,
        brightness: Brightness.dark,
        primaryColorDark: Colors.black,      
        indicatorColor: Colors.white,
        canvasColor: Colors.black,
        // next line is important!
        appBarTheme: AppBarTheme(brightness: Brightness.dark)),
...
