LokotroPayThemeConfig class

Theme configuration for Lokotro Pay.

Pass this to LokotroPayCheckout(themeConfig: ...) to brand the widget. All color fields are optional — anything left null falls back to:

Theme.of(context).colorScheme.* from the host app, or
a clean white-background / near-black-text default if the host has no theme.

Typical usage from a merchant integration:

LokotroPayCheckout(
  configs: LokotroPayConfigs(token: 'app-key'),
  themeConfig: const LokotroPayThemeConfig(
    primaryColor: Color(0xFF2563EB),
    secondaryColor: Color(0xFF1E40AF),
    tertiaryColor: Color(0xFF3BFBDA),
  ),
  ...
)
