# Flutter Typography Measurement

Flutter typography measurement focuses on ensuring that the text within an application is displayed correctly and maintains its intended design across various devices.

## Key Concepts

- **Font Size**: Adjusting font sizes to improve readability. Common sizes include default, small, and large variants.
- **Line Height**: Ensuring appropriate line spacing to enhance text clarity.
- **Letter Spacing**: Adjusting the spacing between characters can impact the overall perception of the text.

## Best Practices

1. **Use Consistent Typography**: Stick to a limited set of fonts throughout the app to maintain a cohesive look.
2. **Responsive Text**: Employ media queries to adjust font sizes and styles based on screen size.
3. **Accessibility Considerations**: Ensure text is legible for people with visual impairments by using appropriate sizes and contrasts.

### Example Code Snippet

Text(
  'Hello, Flutter!',
  style: TextStyle(
    fontSize: 20,

)
```
