… re-arming the pay button When an NWC wallet was connected the pay screen rendered NwcPaymentWidget whenever isWalletConnected && !manualMode, with no check on the _waiting flag the success callback sets. NwcPaymentWidget resets its own _paying flag in its finally block, so right after a successful payment the user saw an enabled "Pay with wallet" button and no confirmation. Tapping again re-sent the same bolt11; the wallet rejected the duplicate, triggering onFallbackToManual and dropping the user onto the QR of an already-settled invoice. Gate the NWC branch on _waiting too (isWalletConnected && !manualMode && !_waiting). Once a payment is detected the branch is skipped and the flow falls through to the invoice/QR layout, which already renders the waitingForPaymentConfirmation spinner in context. No re-armed button, no duplicate send. The manual path is unchanged. Adds a widget test: with a wallet connected and a payable trade the NWC widget is shown; after its onPaymentSuccess callback fires, it is replaced by the confirmation spinner. fakeTrade gains an optional amountSats param so the trade clears the hold-invoice guard. Note: the NWC branch is also missing the cancel button (also fixed for the bond screen in MostroP2P#213). Left out here on purpose: cancelling in the escrow flow is a real trade cancel, not a bond back-out, so the semantics differ and it deserves a separate decision. Closes MostroP2P#244.

- Around line 215-221: Update the invoice/QR rendering flow in the order payment
screen so that when _waiting is true it renders only the waiting state and no
invoice submission controls, including the QR code, payWithLightningWallet
button, or copy/share actions. Preserve the existing wallet-connected and
manual-mode behavior for non-waiting states.

76 - 79: The test should verify that manual invoice controls are unavailable
during the waiting state.

…g, not just the NWC button Review follow-up. The first pass gated only the NWC branch on _waiting and let the flow fall through to the QR/invoice branch, which still rendered the QR code, the pay-with-wallet button and copy/share, so the user could still re-submit the already-settled bolt11 through those. Add a single _waiting guard before both the NWC and QR branches that renders a waiting-only card (spinner + waitingForPaymentConfirmation), so once a payment is detected every submission control is hidden. Revert the NWC condition to !_manualMode and drop the now-unreachable if (_waiting) spinner in the QR branch tail, so _waiting is handled in exactly one place. Extend the widget test to assert that after payment the NWC widget, the QrImageView, the pay-with-wallet button and the copy button are all absent and only the confirmation spinner remains.

Problem
When an NWC wallet is connected, the pay screen renders
NwcPaymentWidgetwheneverisWalletConnected && !manualMode. The_waitingflag set by the payment-success callback was only read in the manual/QR branch, so it had no effect in the NWC branch.NwcPaymentWidgetresets its own_payingflag in itsfinallyblock, so right after a successful payment the user saw an enabled "Pay with wallet" button and no confirmation of any kind.Tapping again re-sent the same bolt11. The wallet rejected the duplicate, which triggered
onFallbackToManualand dropped the user onto the QR of an already-settled invoice. No funds at risk, but the flow looked broken.Fix
Gate the NWC branch on
_waitingas well:isWalletConnected && !manualMode && !_waiting. Once a payment is detected, the NWC branch is skipped and the flow falls through to the invoice/QR layout, which already renders thewaitingForPaymentConfirmationspinner in context. No re-armed button, no duplicate send. The manual path is unchanged.Testing
Adds a widget test (
pay_lightning_invoice_screen_test.dart): with a wallet connected and a payable trade,NwcPaymentWidgetis shown; after itsonPaymentSuccesscallback fires, it is replaced by the confirmation spinner.fakeTradegains an optionalamountSatsparam so the test trade clears the hold-invoice guard (existing callers default to zero, unchanged).flutter analyzeclean; the full trades suite still passes with thefakeTradechange. The widget test drives the exact NWC-success -> spinner path a live payment would; live end-to-end NWC payment isn't reproducible on the current regtest rig, so the test is the primary verification.Open question (cancel button)
As @AndreaDiazCorreia noted in the issue, the NWC branch is also missing the cancel button that #213 added for the bond screen. I left that out of this PR on purpose: cancelling in the escrow flow is a real trade cancel, not a bond back-out, so the semantics differ and it felt like a separate decision. Happy to add it here or as a follow-up, whichever you prefer.
Closes #244.
