如何在Flutter中为Text组件指定等宽字体？

以下是主流UI框架下的实现方式，均会调用系统默认等宽字体，无需额外引入字体文件，适合开发者界面场景：

Flutter #

通过TextStyle指定fontFamily: 'monospace'：

Text(
  "I would like this to be monospace.",
  style: TextStyle(fontFamily: 'monospace'),
)

SwiftUI #

使用.monospaced()字体修饰器，或直接指定等宽设计的系统字体：

// 简洁写法
Text("I would like this to be monospace.")
    .font(.monospaced())

// 可自定义字号的写法
Text("I would like this to be monospace.")
    .font(.system(size: 16, design: .monospaced))

Android Jetpack Compose #

传入FontFamily.Monospace作为fontFamily参数：

Text(
    text = "I would like this to be monospace.",
    fontFamily = FontFamily.Monospace
)

Web/跨平台前端 #

利用CSS的monospace字体族，不同场景的实现示例：

// React Native
<Text style={{ fontFamily: 'monospace' }}>I would like this to be monospace.</Text>

// Web端（原生CSS/任意框架通用）
<span style="font-family: monospace;">I would like this to be monospace.</span>
