swapAddressCheckCoverage method

@override Future<SwapAddressCoverage> swapAddressCheckCoverage()

#390 — the render-only coverage read for the "Check older swap addresses" sheet: how far the wallet has already checked (coveredSwaps) and how many addresses are still to be registered + polled (pending; 0 = nothing outstanding). COUNTS-only. Read-only, side-effect-free — safe to re-pull while the sheet is open. Throws invalid-state on a closed handle.

Implementation

@override
Future<SwapAddressCoverage> swapAddressCheckCoverage() {
  swapAddressCheckCoverageCount++;
  if (swapAddressCheckCoverageThrows != null) {
    return Future<SwapAddressCoverage>.error(swapAddressCheckCoverageThrows!);
  }
  return Future<SwapAddressCoverage>.value(swapAddressCheckCoverageResult);
}
