# SnackbarModel

Auto-generated from the @jbrowse/mobx-state-tree model in the source — see the [developer guide](https://jbrowse.org/jb2/docs/developer_guide/) for concepts. Built into JBrowse core. [View source](https://github.com/GMOD/jbrowse-components/blob/main/packages/core/src/ui/SnackbarModel.tsx).

Adds notifications to a session: the snackbar messages on screen, and the
error shown in the stack-trace dialog.

## Volatiles

| Member | Description |

| **snackbarMessages**<br><code>IObservableArray&lt;SnackbarMessage&gt;</code> |  |
| **errorDialog**<br><code>ErrorDialogState &#124; undefined</code> | the error currently shown in the stack-trace dialog. Kept off the dialog queue so it can stack on top of an already-open dialog (e.g. the one whose action raised the error) instead of waiting behind it |
