Fixes potential StateError crashes and use_build_context_synchronously analyzer warnings by verifying context.mounted after asynchronous operations. This ensures that snackbar feedback is only displayed if the widget remains in the tree after the launchUrl call completes.

  • Added if (!context.mounted) return; check before _showLinkOpenFeedback on link open failure.
  • Added if (!context.mounted) return; check before _showLinkOpenFeedback in the error catch block.

Added `if (!context.mounted) return;` checks after `await launchUrl(...)` in `_openMarkdownLink` within `chat_message_text_part.dart`. This prevents potential runtime crashes and resolves `use_build_context_synchronously` warnings when attempting to show snackbar feedback if the widget has been unmounted.
