dart2js keep function or class

[Super-Crab]

@pragma('dart2js:noElision') is just working for keep unused fields or unused parameters ,I want to keep a function or class, what should I do

[rakudrama]

What are you trying to do? There would be no way to access the function of class.

i wantI want to keep some specific functions even though they are not used, so I would like to know if there is any solution @rakudrama

There is no way to declare that a function or class should be retained by dart2js.

Please could you describe what you are trying to do? If we understand what you want to do we can perhaps suggest a solution for your need.
