**TextArea**

| Prop | Type | Default | Description |
| --- | --- | --- | --- |
| `defaultValue` | `string` | `—` | Initial value for uncontrolled usage.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L13) |
| `error` | `boolean` | `—` | Error state — usually a string for the error message, or a boolean toggle.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L14) |
| `isEditable` | `boolean` | `true` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L17) |
| `helperText` | `string` | `—` | Helper text rendered below the input (hint / error / explanation).[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L18) |
| `id` | `string` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L19) |
| `isReadOnly` | `boolean` | `false` | Keeps the value visible without allowing edits.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L20) |
| `isDisabled` | `boolean` | `false` | Disables user interaction.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L21) |
| `isAutoFocus` | `boolean` | `false` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L22) |
| `label` | `string` | `—` | Visible label rendered alongside the input. Form-library wrappers (Switch, TextField, Checkbox, …) consume this. Not a native HTML attribute on <input>, but conventionally part of the form-control prop surface.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L23) |
| `maxRows` | `number` | `3` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L24) |
| `maxCols` | `number` | `30` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L25) |
| `name` | `string` | `—` | Field name used by forms and Formik bindings.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L26) |
| `placeholder` | `string` | `—` | Hint displayed while the field is empty.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L27) |
| `onChange` | `((value: string) => void)` | `—` | Called when the value changes, with the **value itself** — not the DOM event. TextArea follows the value-first convention this package already exposes through `onChangeText`, so there is no `event.target` to read: onChange={(value) => setBody(value)} // ✅ onChange={(e) => setBody(e.target.value)} // ❌ compile error The parameter is deliberately typed `string` rather than `any`: a DOM-shaped handler is an API mistake, and typing it makes that mistake a compile error instead of a field that silently never updates.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L40) |
| `onChangeText` | `((text: string) => void)` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L41) |
| `onBlur` | `((event: any) => void)` | `—` | Called when the field loses focus, with the blur **event** (not the value).[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L46) |
| `onFocus` | `(() => void)` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L47) |
| `size` | `Size` `"sm"``"md"``"lg"``"xs"``"xl"` | `'sm'` | Size preset for the component.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L48) |
| `shadow` | `ViewProps \| Shadow \| Elevation` | `—` | Shadow or elevation styling.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L49) |
| `shape` | `Shape` `"square"``"rounded"``"pill"``"default"` | `'default'` | Shape preset for the component.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L50) |
| `views` | `TextAreaStyles` | `{ label: {}, helperText: {} }` | Style overrides for the named internal parts.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L51) |

| `variant` | `Variant` `"outline"``"default"``"none"` | `'default'` | Visual treatment of the component.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L53) |
| `rows` | `number` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L54) |
| `cols` | `number` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L55) |
| `isRequired` | `boolean` | `—` | Marks this field as required.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L56) |
| `required` | `boolean` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L57) |
| `labelProps` | `any` | `—` | See the type and source declaration for this property.[Source](https://github.com/rize-network/app-studio-components/blob/main/src/components/Form/TextArea/TextArea/TextArea.props.ts#L58) |

For shared layout, color, and responsive properties, read [Styling & composition](https://app-studio-6167b.web.app/docs/styling) and [Responsive layouts](https://app-studio-6167b.web.app/docs/responsive). Additional native element attributes depend on the target platform.

## Usage guidance

- Give controls a visible label or an accessible name, and verify keyboard interaction. See [Accessibility](https://app-studio-6167b.web.app/docs/accessibility).
- For controlled inputs, update the value from the callback shown in the props table. Keep application state in your component or form library.
- These previews run in the browser. Check [React Native setup](https://app-studio-6167b.web.app/docs/react-native) for platform requirements and differences.
