Toast
Give brief feedback after an application action.
Import
import { NeuToastComponent } from '@neural-ui/native/toast';Examples
Import ExampleComponent into its parent and place <app-example /> inside your application’s root neu-theme. The preview supplies the device frame and safe areas; use the root setup from Installation in your app.
A change you can take back
Edit a project name, save it locally and undo the actual change from the toast. When the notice expires, the confirmed local name stays visible.

API reference
Inputs
| Name | Type | Default | Binding | Description |
|---|---|---|---|---|
| message | string | Required | Input | Message shown to explain a status, notification or decision. |
| duration | number | 0 | Input | Duration in milliseconds. For Toast, 0 keeps the message open until explicitly dismissed. |
| closeLabel | string | 'Dismiss' | Input | Text or accessible name used for close. It does not perform the action by itself. |
| actionLabel | string | '' | Input | Text or accessible name used for main action. It does not perform the action by itself. |
| tone | NeuTone | 'neutral' | Input | Semantic color: neutral, brand, success, info, warning or danger. The accent value remains a compatible alias for brand. Colors use NeuTheme tokens; explain statuses with words as well as color. |
Models
| Name | Type | Default | Binding | Description |
|---|---|---|---|---|
| open | boolean | false | Model · two-way | Whether the presentation or message is requested to be open. Bind a writable signal with [(open)]. |
Outputs
| Name | Payload | When it emits |
|---|---|---|
| openChange | boolean | Emits the updated open value. [(open)] binds this output together with its model input. |
| action | void | Requests the component’s action. The payload, when present, identifies the action or item. |
| dismissed | void | Reports completion of native dismissal. |
Model state
Bind the signal with [(modelName)] without calling it. Use modelName() to read its value.
