Resolves the configured absolute HTTP(S) base URL.

Implementation

Uri resolve(
  Map<Object?, Object?> endpoint, {
  Map<String, String>? environment,
}) {
  final inline = endpoint['baseUrl'];
  final fromEnvironment = endpoint['baseUrlFrom'];
  if (inline != null && fromEnvironment != null) {

      'Endpoint must declare exactly one of baseUrl or baseUrlFrom',
    );
  }
  final value = inline is String
      ? inline
      : fromEnvironment is String
      ? (environment ?? Platform.environment)[fromEnvironment]
      : null;
  if (value == null || value.trim().isEmpty) {
    final name = fromEnvironment is String
        ? ' environment $fromEnvironment'
        : '';
    throw FormatException('Endpoint base URL$name is not configured');
  }
  final uri = Uri.tryParse(value);
  if (uri == null || !uri.hasScheme || !uri.hasAuthority) {
