Jetpack Compose是否有类似Flutter ColorScheme.fromSeed的配色生成功能？

Jetpack Compose（含Compose Multiplatform）可通过以下方案实现类似Flutter ColorScheme.fromSeed的功能，生成符合Material Design规范的明暗主题配色：

一、官方内置方案：Compose Material3 ColorScheme.fromSeed() #

从Compose Material3 1.1.0版本开始，官方提供了与Flutter完全对等的API，直接通过种子色生成全套协调的ColorScheme，自动适配明暗主题。

使用示例 #

import androidx.compose.material3.ColorScheme
import androidx.compose.material3.darkColorScheme
import androidx.compose.material3.lightColorScheme
import androidx.compose.material3.fromSeed
import androidx.compose.ui.graphics.Color

// 定义种子色
val seedColor = Color(0xFF6200EE)

// 生成亮色主题配色
val lightColorScheme: ColorScheme = lightColorScheme.fromSeed(seedColor = seedColor)

// 生成暗色主题配色
val darkColorScheme: ColorScheme = darkColorScheme.fromSeed(seedColor = seedColor)

生成的ColorScheme包含primary、secondary、tertiary、background、surface、error等全套色彩，完全遵循Material 3的色彩协调规则。

二、低版本兼容/自定义扩展方案 #

如果项目使用低于1.1.0的Material3版本，或需要定制化色彩逻辑，可使用Google官方的Material Color Utilities库（Material 3色彩系统的底层实现依赖）。

实现步骤 #

1. 添加依赖（Material3 1.1.0+已内置该库，无需重复添加）

dependencies {
    implementation "com.google.android.material:material-color-utilities:1.2.0"
}

2. 手动实现种子色生成逻辑

import androidx.compose.material3.ColorScheme
import androidx.compose.material3.darkColorScheme
import androidx.compose.material3.lightColorScheme
import androidx.compose.ui.graphics.Color
import com.google.android.material.color.utilities.Hct
import com.google.android.material.color.utilities.MaterialColors

fun generateColorSchemeFromSeed(seedColor: Color, isDark: Boolean): ColorScheme {
    val hctSeed = Hct.fromInt(seedColor.value.toInt())
    val materialColors = MaterialColors.hctToColorScheme(hctSeed, isDark)
    
    return if (isDark) {
        darkColorScheme(
            primary = Color(materialColors.primary),
            onPrimary = Color(materialColors.onPrimary),
            secondary = Color(materialColors.secondary),
            onSecondary = Color(materialColors.onSecondary),
            tertiary = Color(materialColors.tertiary),
            onTertiary = Color(materialColors.onTertiary),
            background = Color(materialColors.background),
            onBackground = Color(materialColors.onBackground),
            surface = Color(materialColors.surface),
            onSurface = Color(materialColors.onSurface),
            error = Color(materialColors.error),
            onError = Color(materialColors.onError)
        )
    } else {
        lightColorScheme(
            primary = Color(materialColors.primary),
            onPrimary = Color(materialColors.onPrimary),
            secondary = Color(materialColors.secondary),
            onSecondary = Color(materialColors.onSecondary),
            tertiary = Color(materialColors.tertiary),
            onTertiary = Color(materialColors.onTertiary),
            background = Color(materialColors.background),
            onBackground = Color(materialColors.onBackground),
            surface = Color(materialColors.surface),
            onSurface = Color(materialColors.onSurface),
            error = Color(materialColors.error),
            onError = Color(materialColors.onError)
        )
    }
}

// 调用示例
val seedColor = Color(0xFF6200EE)
val lightScheme = generateColorSchemeFromSeed(seedColor, isDark = false)
val darkScheme = generateColorSchemeFromSeed(seedColor, isDark = true)

三、Compose Multiplatform 适配 #

上述方案完全支持Compose Multiplatform：

• 内置ColorScheme.fromSeed()只需确保Material3依赖版本≥1.1.0；
• Material Color Utilities是纯Kotlin库，可直接在通用模块中使用，无需平台特殊处理。
