Basic Usage

import Button from '@/components/common/buttons/button';
const MyComponent = () => {
    return (    
        <Button onPress={() => console.log('Button pressed')}>
            Click me
        </Button>
    );
}

​
With Loading State

import Button from '@/components/common/buttons/button';
import { useState } from 'react';

function LoadingButton() {
  const [isLoading, setIsLoading] = useState(false);

  const handlePress = async () => {
    setIsLoading(true);
    // Perform async operation
    await someAsyncOperation();
    setIsLoading(false);
  };

  return (
    <Button
      onPress={handlePress}
      loading={isLoading}
    >
      Submit
    </Button>
  );
}

​
With Icon

import { MaterialIcons } from '@expo/vector-icons';
import Button from '@/components/common/buttons/button';

function IconButton() {
  return (
    <Button
      onPress={() => {}}
      icon={<MaterialIcons name="send" size={24} color="white" />}
      iconPosition="right"
    >
      Send Message
    </Button>
  );
}

​
Custom Styling

Don’t forget to use constants/appConstants.ts to defining your theme.

import Button from '@/components/common/buttons/button';

export const StyledButton = () => {
  return (
    <Button
      onPress={() => {}}
      bgColor="#FF5733"
      borderColor="#CC4427"
      borderWidth={2}
      height={50}
      style={{
        marginVertical: 10,
        width: '90%'
      }}
    >
      Custom Style
    </Button>
  );
}

​
Styling

The button comes with default styles that can be customized:

  • Default border radius from BORDER_RADIUS.sm
  • Flexible height (default from BUTTON_HEIGHT.md)
  • Pressed state reduces opacity to 0.8 and scales to 0.99
  • Disabled state reduces opacity to 0.5
  • Icons have horizontal margin from MARGIN.sm

​
Theme Integration

The button automatically integrates with your app’s theme system using the useTheme hook:

import Button from '@/components/common/buttons/button';

export const ThemedButton = () => {
    return (
        <Button
            onPress={() => {}}
            // bgColor will default to Colors[mode].button if not specified
        >
            Themed Button
        </Button>
    );
}

​
Notes

  • Haptic feedback is automatically triggered on button press (native platforms only)
  • Loading state automatically disables the button
  • The button supports both single and array style props for flexible styling
  • Icons are wrapped in a View container with horizontal margin
  • The component is fully type-safe with TypeScript

​
Best Practices

  1. Always provide a meaningful onPress handler
  2. Use loading state for async operations
  3. Provide appropriate feedback for disabled states
  4. Consider using icons to enhance visual communication
  5. Maintain consistent styling across your application
  6. Use the theme system for consistent color schemes
