flutter pub add rainbow_color根據套件公開資料產生的選型評估，僅供參考。
RainbowColor 是一個 Flutter/Dart 套件，透過將數值範圍對應至平滑且視覺上吸引人的色彩漸層，簡化多色插值。它讓開發者能根據輸入值產生無縫的多種顏色過渡，非常適合資料視覺化、進度指示器與動態 UI 元件。此套件支援所有主要平台，並可輕鬆整合至現有的 Flutter 專案中。僅需最少設定，即可提供一致且高品質的色彩過渡，無需複雜的自訂邏輯。

RainbowColor simplifies interpolation a numerical domain onto a multi-color range. RainbowColor accepts a numerical domain
(i.e. a start and end number) and a spectrum of two or more colors, and offers the list access operator ([]) for
interpolation.
This package also provides RainbowColorTween, a multi-color variant of the standard ColorTween, eliminating the need
to build more complex TweenSequence for equal-weight transitions.
To interpolate a color among the spectrum, use the list access operator, e.g.
import 'package:rainbow_color/rainbow_color.dart';
var rb = Rainbow(spectrum: [Color(0xFFFF0000), Color(0xFFFFFFFF), Color(0xff00ff00)],
rangeStart: -10,
rangeEnd: 10);
Color warmColor = rb[-9.32];
Color coldColor = rb[8.44];
Or use RainbowColorTween in place of ColorTween to interpolate among multiple colors instead of two.
@override
void initState() {
super.initState();
_controller = AnimationController(duration: widget.duration, vsync: this);
_clAnim = RainbowColorTween([Color(0x33FFAAAA),
Color(0x33000000),
Color(0x00000000)]).animate(_controller)
..addListener(() {
setState(() {});
});
}
This is a Flutter-oriented version of the vanilla Dart package rainbow_vis.
