## Flutter Typography Measurement

To measure typography in Flutter, you can utilize the `Text` widget and various typography styles such as `TextStyle`. Here are the key components for measuring typography:

### Key Properties
- **fontSize**: Sets the size of the text.
- **fontWeight**: Specifies the weight of the font (e.g., `FontWeight.bold`).
- **fontFamily**: Defines the font family.
- **letterSpacing**: Adjusts the space between letters.
- **wordSpacing**: Adjusts the space between words.
- **height**: Sets the line height.

### Example
```dart
Text(
  'Hello, Flutter!',
  style: TextStyle(
    fontSize: 24,
    fontWeight: FontWeight.bold,
    letterSpacing: 1.5,
    height: 1.2,
  ),
)
```

By tweaking these properties, you can effectively measure and control the typography in your Flutter applications.
