What is package naming convention used in Dart?

Question

Is there a naming convention for Dart packages? Is there maybe a document that describes patterns? I have trouble figuring out naming convention for package names that consist of multiple words. For example, should I use placeView, PlaceView, place_view, or something else?

Answer 1

This is documented on the name section of Pubspec Format documentation.

It should be all lowercase, with underscores to separate words, just_like_this. Stick with basic Latin letters and Arabic digits: [a-z0-9_] and ensure that it’s a valid Dart identifier (i.e. doesn’t start with digits and isn’t a reserved word).

Try to pick a name that is clear, terse, and not already in use.

Answer 2

There doesn't seem to be a convention for it, but most of the time, I see lowercase_words_with_underscore being used, both for libraries and packages.

For libraries inside packages, some people also use dots for grouping, for example my_package.lib_1 and my_package.lib_2.

It's all personal preference, I guess.
