This tip : https://github.com/vandadnp/flutter-tips-and-tricks/blob/main/tipsandtricks/convert-enums-to-strings-in-dart/convert-enums-to-strings-in-dart.md

is out of date because we now have enumValue.name since Dart 2.15 so I think this tip can be removed 😉

This tip is overly complicated, you can just do enumValue.index : https://github.com/vandadnp/flutter-tips-and-tricks/blob/main/tipsandtricks/enum-associated-values-in-dart/enum-associated-values-in-dart.md

Maybe a note would be helpful, to use that with caution. The creation of the error-value could be expensive and with your approach, I would create that object all the time, even if I don't need it. That is the reason, as far as I know, to pass a creation function into it. Just my thought to avoid bad designs for newcomers to dart.

Thanks for all your tips, I like it a lot.

Hey! Thanks for a very cool repo ✌️

Would be nice if the release message contained the tip itself or at least a link to the new section. So if I see the release in the feed, I could just read it by entering the release page.

Hello Vandad, that's for creating such a useful project. I've been playing around with loading the tips and trick in the terminal for a while now using this method Flutter Tips and Tricks in Terminal but just now the link doesn't show all the images and dart code just the .md files. Is there a new method to get each tip with its image and source code now? I'm creating an open source app using this repo and would really like it to work out.

I also can't get the dart files now, https://raw.githubusercontent.com/vandadnp/flutter-tips-and-tricks/main/tipsandtricks/implementing-zip-and-tuples-in-dart/implementing-zip-and-tuples-in-dart.dart This like gives me a 404 error. But I can access the .jpg freely.

Using classes as enum has become obsolete since Dart 2.17, this tip could be removed !

You use the reduce method to get the sum of list items in dart. Calculating the Sum of List Items in Dart

Actually there is a built-in way for doing that:

import 'package:collection/collection.dart';

void main() {
  final list = [1, 2, 3, 4];
  final sum = list.sum;
  print(sum); // prints 10
  final average = list.average; 
  print(average); // prints 2.5
}

In "Factory Constructors in Dart" there is no definition for "Rect".

Great tips thanks, the only problem is I can't load this page entirely. I think it's too heavy to load on a single page causes browser to stuck.

As suggested at https://github.com/vandadnp/flutter-tips-and-tricks/blob/main/tipsandtricks/default-value-for-optionals-in-dart/default-value-for-optionals-in-dart.md

I declared:

extension OrDefault<T> on T {
  T get orDefault {
    final value = this;
    if (value == null) {
      return {
        int: 0,
        String: '',
        double: 0.0,
        num: 0,
        bool: false,
        Map: {},
        List: [],
        Set: {},
      }[T] as T;
    } else {
      return value;
    }
  }
}

  test('Test ObjectExtension.orDefault()', () async {
    const int? nullInt = null;
    expect(nullInt.orDefault, 0); // fails since T is int? and returns null instead of 0.
  });

Hi. The extension method to could be made more optimized or idiomatic (since its return type is declared as Iterable) by avoiding unnecessary array creation. The code won't be as pretty though 😃

vs

extension To on int {
  Iterable<int> to(int other, [bool inclusive = true]) sync* {
    if (other > this) {
      for (int i = this; i < other; i++) yield i;
    } else {
      for (int i = this; i > other; i--) yield i;
    }

    if (inclusive) yield other;
  }
}

43 - Converting Lists to Maps in Dart

const list = ['this','is','a','long','text'];

final map = {for (final s in list) s:s.length}; /// <= this way!

void main() {
  for (final e in map.entries) {
    print('"${e.key}" length is ${e.value}');
  }
}

Typo in "365 - Recoveringg Stream Errors in Flutter"

Likely you planned saying "Recovering" (single G)?

RE: https://github.com/vandadnp/flutter-tips-and-tricks/blob/main/tipsandtricks/null-aware-infix-operators-in-dart/null-aware-infix-operators-in-dart.md

Having:

T? operator +(final T? other) {
  final shadow = this;
  if (shadow != null) {
    return shadow + (other ?? 0) as T;
  } else {
    return null;
  }
}

and the test:

test('Test null + operator', () {
    int? var1;
    var1++;
    var1 += 1;
    var1 = var1 + 1;
    var1 = 2;
    var1++;
    var1 += 1;
    var1 = var1 + 1;
    expect(var1, 5);
}

The test runs successfully but with code coverage we can see that the line

return shadow + (other ?? 0) as T;

never gets called which leads me to the speculation that shadow always equals to NULL when the extension is called and the extension is not "attached" if T is not null.
