flutter pub add ansicolor根據套件公開資料產生的選型評估，僅供參考。
ansicolor 是一個 Dart 庫，為終端輸出提供 xterm-256 顏色支援，讓開發者能夠自訂終端日誌中的文字前景色與背景色。它能無縫整合至跨平台的 Flutter 應用中，增強除錯可見度與日誌可讀性。此套件非常適合希望在不依賴外部工具的情況下為終端輸出增添視覺區別的開發者。透過簡潔語法，它直接在終端中支援廣泛的顏色與格式選項。

Feel like you're missing some color in your terminal programs? Use AnsiPen to add ANSI color codes to your log messages.
Easy to disable for production, just set color_disabled = true and all codes will be empty - no re-writing debug messages.
Note: color_disabled is a global variable for all pen colors.
Note: Be mindful of contrasting colors. If you set "bright white" foreground and don't adjust the background, you'll have a bad time with lighter terminals.
Foreground to bright white with default background:
AnsiPen pen = AnsiPen()..white(bold: true);
print(pen("Bright white foreground") + " this text is default fg/bg");
Background as a peach, foreground as white:
AnsiPen pen = AnsiPen()..white()..rgb(r: 1.0, g: 0.8, b: 0.2, bg: true);
print(pen("White foreground with a peach background"));
If color isn't working for you; try setting ansiColorDisabled = false;. We're relying on the stdio object to inform us of ANSI terminal support. Sometimes this is wrong.
Prior versions of this library just turned on color by default.
If you want a specific color, you can call the xterm() with the index listed in the rainbow below. To show the rainbow on your own terminal, pub run examples/ansicolor.dart
