becklinks_core

The shared base of the Beck Links Flutter packages that are not the deep linking SDK (becklinks_force_update, later becklinks_rating): API key checks, the network client with retries, one exception type and a small logger.

You normally do not install it yourself: install a feature package such as becklinks_force_update and this comes with it. Deep linking has its own package, becklinks_flutter.

final client = BeckLinksApiClient(
  apiKey: 'pk_live_YOUR_KEY',
  sdkName: 'my_package',
  sdkVersion: '1.0.0',
);
final answer = await client.postJson('/v1/sdk/app-version', {'platform': 'ios', 'app_version': '2.1.0'});

• Keys: pk_test_... and pk_live_... only; a secret key (sk_...) is refused with the advice to revoke it.
• Retries: network failures, 5xx and 429 are retried (twice by default) with backoff; a Retry-After longer than five seconds is not waited for.
• Errors: every failure is a BeckLinksException with a code (network, invalid_key, rate_limited, invalid_request, server, ...), the API's own apiCode and the request ID.
