formatQuotaUsedLimit function

String formatQuotaUsedLimit(ProviderQuota? quota)

Renders the used/limit column: unknown for a null quota (capability absent or fetch failed — never a null literal, E2), unmetered for billing-free providers, $48.20/$150 when both sides are known, $48.20/no cap for uncapped prepaid, unlimited when nothing is reported at all, …/$150 when only the limit is known.

Implementation

String formatQuotaUsedLimit(ProviderQuota? quota) {
  if (quota == null) return 'unknown';
  if (quota.isUnmetered || quota.unit == QuotaUnit.unmetered) return 'unmetered';
  final used = formatQuotaAmount(quota.used, quota.unit);
  final limit =
      quota.limit == null ? null : formatQuotaAmount(quota.limit, quota.unit);
  if (quota.used == null && limit == null) return 'unlimited';
  if (limit == null) return '$used/no cap';
  return '$used/$limit';
}
