fromDeprecatedAccounts static method

AuthPolicy? fromDeprecatedAccounts(
  1. List<Account>? accounts
)

The policy the deprecated authenticateAs list stands for: the first account it names that can sign, and nobody when none can.

Implementation

static AuthPolicy? fromDeprecatedAccounts(List<Account>? accounts) {
  if (accounts == null || accounts.isEmpty) {
    return null;
  }
  for (final account in accounts) {
    if (account.signer.canSign()) {
      return AuthPolicy.allow(account);
    }
  }
  return const AuthPolicy.never();
}
