243-294: 🩺 Stability & Availability | 🟠 Major | ⚡ Quick winMove the in-progress guard above the permission branch.
The
CCID_READER_CONNECT_IN_PROGRESScheck at Lines 244-247 only runs whenusbManager.hasPermission(device)is false. After the user grants permission,hasPermissionreturns true immediately, but theACTION_USB_PERMISSIONbroadcast arrives later, soreader.resultis still set.A second
connectcall in that window takes theelsebranch at Line 276 and connects directly. Two failures follow:
- Line 289 writes
reader.copy(ccid = ccid)from the snapshot read at Line 226, which still carries the pendingresult. The receiver then callsconnectToInterfaceagain at Line 65 and overwritesccidat Line 76. The firstCcidand itsUsbDeviceConnectionare orphaned.- Both the direct call and the broadcast complete their own
Resultwith success, so the reader is reported connected twice over two distinct USB connections.Check the pending result once, before the permission branch.
🐛 Proposed fix

listReaderswhile a permission request is pending, the old entry is discarded with itsResult. The permission broadcast then hits the "Reader not found" branch at Lines 39-42 and returns, so the Dart future never completes.Consider tracking pending connect results outside the reader map, keyed by device name and interface index.

The two Android CI failures are unrelated to this PR: the example pins Gradle 8.11.1 while the workflow tracks Flutter stable, which now requires Gradle >= 8.14.0. The same Android implementation builds successfully in canokey-console with a current Gradle toolchain. |

🌐 Web query:
actions/checkout v5 persist-credentials default true GitHub documentation
💡 Result:
In the actions/checkout v5 GitHub Action, the persist-credentials input defaults to true [1][2]. When set to true (the default), the action configures the authentication token or SSH key in the local git configuration [1][3]. This allows your workflow scripts to run authenticated git commands within that job [1]. The action automatically removes this credential during the post-job cleanup step [1][3]. If you wish to disable this behavior, you must explicitly set persist-credentials to false [1][3].

Disable checkout credential persistence.
actions/checkout@v5 stores the job token in the local Git configuration by default. Later repository-controlled commands can read this token. Set persist-credentials: false unless authenticated Git operations are required.
