FormatException: Message corrupted in StandardMessageCodec.readValue during state restoration

[seelrd]

Steps to reproduce

Can't reproduce, but my app is using simple restorable variables (RestorableString, etc.) and navigator.restorablePush functions.

Expected results

Shouldn't crash during state restoration. This is a very rare problem.

Actual results

App crashes on iOS during fresh app start very rarely. The error is "FormatException: Message corrupted" in StandardMessageCodec.readValue (you can see it in the logs below) during state restoration. I have no other logs, as the app crashes immediately (at state restoration), none of my code runs.

As writing an incorrect value to a restorable variable would cause an error while modifying the variable, and an error like that doesn't occur, I believe this is a bug in Flutter.

Code sample

Code sample

```dart Navigator.of(context).restorablePush(ConversationPage.routeBuilder, arguments: {'conversation': conversation.toJSON()}); ``` ```dart late RestorableTextEditingController inputController; RestorableInt replyMessageId = RestorableInt(0); RestorableString chatInput = RestorableString(""); RestorableBool isSendingImage = RestorableBool(false); ``` ```dart @override void initState() { super.initState(); inputController = RestorableTextEditingController(); } ``` ```dart @override void dispose() { inputController.dispose(); super.dispose(); } ``` ```dart @override void restoreState(RestorationBucket? oldBucket, bool initialRestore) { registerForRestoration(chatInput, 'chatInput'); registerForRestoration(inputController, 'inputController'); registerForRestoration(replyMessageId, 'replyMessageId'); registerForRestoration(isSendingImage, 'isSendingImage'); String savedInput = context.read().chatInputs[widget.conversation.id] ?? ""; if (inputController.value.text.isEmpty && savedInput.isNotEmpty) { inputController.value.text = savedInput; chatInput.value = savedInput; } } ```
