How can I call a function from a method of the same name?

Question

I want to have a print method in my class, also I want to be able to use print inside it

example:

class A {
  String val;
  void print() {
    print(val);
  }
}

using print will refer to the method of class A, how can I specify the full path of the method I want to call?

Answer 1

A couple of different ways to resolve the name conflict:

• As Christopher Moore mentioned, you can explicitly import dart:core with a prefix. Note that if you don't want to prefix everything from dart:core, you could import it twice, once into the global namespace and again into the prefixed namespace:

  import 'dart:core';
  import 'dart:core' as core;
  

  Then you would be able to explicitly use core.print within your print method and use print normally everywhere else.

  Note that if you have a method trying to call a global function with the same name within the same Dart library, you could split your code into multiple files, or your library could import itself with a prefix:

  foo.dart:

  import 'foo.dart' as foo;
  
  class SomeClass {
     void f() => foo.f();
  }
  
  void f() {
     // Do stuff.
  }
  

• You alternatively could explicitly create another reference to the normal print function with a different name:

  final _print = print;
  
  class A {
    String val;
    void print() {
      _print(val);
    }
  }
  

Answer 2

I'm assuming that you're trying to call the print function of dart:core.

You can explicitly import dart:core and specify a prefix for it with the as keyword:

import 'dart:core' as core;

class A {
  core.String val;
  void print() {
    core.print(val);
  }
}

Likely the biggest issue with this is now you have to have to prefix everything that's in dart:core like the String in your example.

Answer 3

import "dart:core";
import "dart:core" as core show print;

class Class {
  static print(_string) {
    if (kDebugMode) {
      core.print(_string);
    }
  }
}
