# Flutter Typography Measurement

## Introduction
In Flutter, typography is an essential part of the UI design. It helps convey information effectively and can significantly impact the overall look and feel of your application.

## Key Typography Metrics
Understanding typography metrics is crucial for creating a visually appealing design. Here are some key terms you should be familiar with:

- **Font Size**: The size of the text. It is usually measured in points.
- **Line Height**: The vertical space between lines of text. Adjusting this can improve readability.
- **Letter Spacing**: The space between characters in a word.
- **Font Weight**: The thickness of the text characters, which can emphasize certain parts of your content.

## Example of Typography in Flutter

```dart
Text(
  'Hello, Flutter!',
  style: TextStyle(
    fontSize: 24,
    fontWeight: FontWeight.bold,
    letterSpacing: 1.5,
  ),
)
```
