Theming

By default the SDK matches your app. At runtime it reads your theme's colors, fonts, corner radius, button style, type scale and dark mode, and the rewards UI uses them. Layout and motion come from the Flyy UI variant; your app supplies the colors, fonts and shapes.

What's captured

	Android	iOS
Colors	Material 3 / Material 2 / AppCompat theme attrs, Compose MaterialTheme.colorScheme	Tint and system colors, trait collection
Fonts	res/font files and <font-family> XML, Compose Font(R.font.x)	Fonts listed in UIAppFonts
Shapes	shapeAppearance*, materialButtonStyle, Compose shapes	—
Text size	fontScale / Compose density	Dynamic Type
Dark mode	Theme / uiMode	userInterfaceStyle, SwiftUI colorScheme

Changes apply live. Switch dark mode or font size and open Flyy surfaces update without reloading.

Contrast is checked: any text color below WCAG 4.5:1 (3:1 for button labels) is replaced with black or white.

Overrides

Android

Flyy.start(this) {
    partnerId = "…"
    themeColor = "#7C3AED"
    hostTheme = mapOf(
        "colors.primary" to "#C2138F",
        "shape.button" to 24,
    )
}

// Compose: read the theme explicitly, inside your app theme
Flyy.hostTheme(MaterialTheme)

iOS

Flyy.initialize(FlyyConfig(
    partnerId: "…",
    themeColor: "#7C3AED",
    hostTheme: ["colors.primary": "#C2138F", "shape.button": 24]
))

Precedence

Highest first:

1. Per-placement theme set in GameStudio
2. Explicit config — themeColors, custom fonts, themeColor
3. Captured app theme (matchHostTheme)
4. The UI variant's defaults

To stop matching your app, set matchHostTheme = false. Font scale is always respected for accessibility.

v1 theme setters

setThemeColor, setThemeColors, setDarkThemeColor and setCustomFontName still work and rank at level 2.
