| |
| From the [style guide](https://dart.dev/guides/language/effective-dart/style/): |
| |
| **DO** name types using UpperCamelCase. |
| |
| Classes and typedefs should capitalize the first letter of each word (including |
| the first word), and use no separators. |
| |
| **GOOD:** |
| ```dart |
| class SliderMenu { |
| // ... |
| } |
| |
| class HttpRequest { |
| // ... |
| } |
| |
| typedef num Adder(num x, num y); |
| ``` |
