memoizer_generator 1.0.0-nullsafety

Creates a separate version of a function and extending memoize

memoizer

Use if you want to cache the results of previous function calls for efficiency reasons.

Basic usage

1. Convert your function from

int getUserId(String name) {
  return Firebase().getUserIdByName(name);
}

2. into a callable class, and decorate with the @memoize annotation

@memoizer
class GetUserId {
  int call(String name) {
    return Firebase().getUserIdByName(name);
  }
}

3. call it and the results will be cached

var getUserId = GetUserId();
var result1 = getUserId("Adrian");
var result2 = getUserId("John");
var result3 = getUserId("Adrian"); //this will save a call to the server as the results would have already been cached
