CrossmintClientConfig

Final Class Configuration for CrossmintClient.

final class CrossmintClientConfig extends CrossmintApiConfig

Extends CrossmintApiConfig (the shared base shape used across all Crossmint SDK platforms) with the Flutter-specific plug-points authStorage, logger, refreshRoute, and logoutRoute.

const config = CrossmintClientConfig(
  apiKey: 'YOUR_STAGING_API_KEY',
  appScheme: 'com.your.app',
);

Use a client key (ck_*) for frontend apps — they require origin for auth. Use a server key (sk_*) only in server contexts; it needs no origin.
