Function AlertComponent

AlertComponent - Toast-style alert notification with auto-dismiss

AlertComponent is a simple yet effective React Native modal for displaying temporary alert messages. It supports success/danger styling, auto-dismiss with configurable duration, and manual dismissal by tapping the alert.

Key Features:

  • Two alert types (success: green, danger: red)
  • Auto-dismiss with configurable duration
  • Manual dismissal by tapping
  • Customizable text color
  • Centered overlay presentation
  • Smooth show/hide transitions

UI Customization: This component can be replaced via uiOverrides.alertComponent to provide a completely custom alert implementation.

Component

Example

// Basic usage - Display success alert with auto-dismiss
import React, { useState } from 'react';
import { AlertComponent } from 'mediasfu-reactnative-expo';

function App() {
  const [alertVisible, setAlertVisible] = useState(false);
  
  const showSuccessAlert = () => {
    setAlertVisible(true);
  };

  return (
    <>
      <Button title="Show Success" onPress={showSuccessAlert} />
      <AlertComponent
        visible={alertVisible}
        message="Operation completed successfully!"
        type="success"
        duration={3000}
        onHide={() => setAlertVisible(false)}
        textColor="white"
      />
    </>
  );
}

Example

// Danger alert with custom duration
<AlertComponent
  visible={showError}
  message="Failed to connect to server. Please try again."
  type="danger"
  duration={5000}
  onHide={() => setShowError(false)}
  textColor="white"
/>

Example

// Using uiOverrides for complete alert replacement
import { MyCustomAlert } from './MyCustomAlert';

const sessionConfig = {
  credentials: { apiKey: 'your-api-key' },
  uiOverrides: {
    alertComponent: {
      component: MyCustomAlert,
      injectedProps: {
        position: 'top',
        animation: 'slide',
      },
    },
  },
};

// MyCustomAlert.tsx
export const MyCustomAlert = (props: AlertComponentOptions & { position: string; animation: string }) => {
  return (
    <Modal visible={props.visible} transparent>
      <View style={{ position: 'absolute', [props.position]: 20 }}>
        <Text style={{ color: props.type === 'success' ? 'green' : 'red' }}>
          {props.message}
        </Text>
      </View>
    </Modal>
  );
};

Properties

OptionalpropTypes

propTypes?: WeakValidationMap<AlertComponentOptions>

Used to declare the types of the props accepted by the component. These types will be checked during rendering and in development only.

We recommend using TypeScript instead of checking prop types at runtime.

See

React Docs

OptionalcontextTypes

contextTypes?: ValidationMap<any>

Deprecated

Lets you specify which legacy context is consumed by this component.

See

Legacy React Docs

OptionaldefaultProps

defaultProps?: Partial<AlertComponentOptions>

Used to define default values for the props accepted by the component.

See

React Docs

Example

type Props = { name?: string }

const MyComponent: FC<Props> = (props) => {
  return <div>{props.name}</div>
}

MyComponent.defaultProps = {
  name: 'John Doe'
}

Deprecated

Use values for destructuring assignments instead.

OptionaldisplayName

displayName?: string

Used in debugging messages. You might want to set it explicitly if you want to display a different name for debugging purposes.

See

Legacy React Docs

Example


const MyComponent: FC = () => {
  return <div>Hello!</div>
}

MyComponent.displayName = 'MyAwesomeComponent'
