Flutter FlutterLogo 控件介紹

1、使用方法

FlutterLogo({
    Key key,
    this.size,//設置大小
    this.colors,//設置顏色
    this.textColor = const Color(0xFF616161),//用於在徽標上繪製「Flutter」文本的顏色，若是樣式爲 FlutterLogoStyle.horizntal或FlutterLogoStyle.stacked。適當的顏色是const Color(0xFF616161)（中灰色），白色背景。
    this.style = FlutterLogoStyle.markOnly,//是否以及在何處繪製「顫動」文本。默認狀況下，僅繪製徽標自己
    this.duration = const Duration(milliseconds: 750),//若是更改樣式，顏色或 textColor屬性，則動畫的時間長度
    this.curve = Curves.fastOutSlowIn,//若是樣式，顏色或textColor 發生更改，則會生成徽標動畫的曲線。
  })
