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. save an instance and call it; the results will be cached
var getUserId = Memo_GetUserId();
var result1 = getUserId("Adrian");
var result2 = getUserId("John");
var result3 = getUserId("Adrian"); //this will save a call to the server as the results have already been cached
4. install the dependencies if you have not done so
dependencies:
  memoizer_annotation: ^1.0.0-nullsafety

dev_dependencies:
  build_runner: ^1.7.3
  memoizer_generator: ^1.0.0-nullsafety
5. run build runner
pub run build_runner build
