I recently started a series of daily tweets about easy ways to improve your Dart & Flutter code. I called this Easy Wins.
To make these easier to find, I'm sharing 7 tips every week here on my website.
Entire series here:
- Dart & Flutter Easy Wins 1-7
- Dart & Flutter Easy Wins 8-14
- Dart & Flutter Easy Wins 15-21
- Dart & Flutter Easy Wins 22-28
- Dart & Flutter Easy Wins 29-35
- Dart & Flutter Easy Wins 36-42
22. Use `toStringAsFixed(n)` to format a number with n decimal places.
23. Did you know? Dart supports string multiplication.
24. One constructor is not enough? Use named constructors and initializer lists for more ergonomic APIs.
25. Prefer factory constructors to static methods for deserialization.
More info here: The difference between a "factory constructor" and a "static method"
26. Need a class that can only be instantiated once (aka singleton)? Use static instance variable with a private constructor.
27. Need a collection of unique items? Use a set rather than a list.
28. Use inheritance to model ISA relationships.
More tips coming next week. Subscribe via RSS for updates!
Happy coding!
