Immutability Resources for Dart

Resources for studying immutability in the context of OOP languages.

The numbering below is simply for differentiation.

~90% of the resources below come from Marcelo Glasberg.

Reflection in Dart

Unfortunately, [since mirrors currently bloat compiled code][no_support_mirrors], it isn't supported for Flutter or web apps. A [workaround][source_gen_tutorial] would be to use a package like [source_gen][source_gen].

dart:mirrors

Most of the info here, comes from [Understanding Reflection and Annotations in Dart tutorial][reflection_tutorial], from the Fullstack Dart and Flutter Tutorials YouTube channel. He also created a [gist][gist_tutorial] with it.

상대방의 돌로 2수 두세요 play two moves with your opponent stones..... Illegal moves are not allowed
야호! Play two moves wherever you want
꽝 pass
가위,바위,보를 winner can change the opponent's stone to his buke....the one who has more buke shapes, gets two captured stone.
1선에 3수를 play 3 moves on the first line
공짜 한수 play one move and get another card
상대에게 내 이름을 물어보세요 ask your opponent: what is my name? If he knows u give 2 points
키가 큰 사람이 작은사람에게 taller gives 2points to the smaller one

Linux Heroic Commands

From a tutorial somewhere...

sudo !! : re-executing the last command as sudo.
Ctrl + X + E in the terminal to open an editor.
Create a super fast RAM disk (hard drive on the RAM):
```
mkdir -p /mnt/ram
```

mount -t tmpfs /mnt/ram -o size=8192M

Gathering Code Coverage

Install the coverage package:
```
pub global activate coverage
```
Create a test file for running all of the tests.

Run — in this case, the file with all of the tests is called .test_coverage.dart —:

dart --pause-isolates-on-exit --disable-service-auth-codes --enable-vm-service=NNNN test/.test_coverage.dart

Mixins vs Extensions in Dart

The Major Differences

Mixins allow for an adapted multiple inheritance.
- Though they have the limitation that you cannot have mixins inheriting mixins.
Extensions let you add new methods to a class but not state (new instance variables).
- But you can use stuff like the [Expando object][expando].
- They can't override methods either.

	/// To run this, you can simply use:
	///
	/// ```sh
	/// dart different_fixed_list_initializations.dart
	/// ```

	/// For more, check out the [`List` docs][list_docs].
	///
	/// The `UnmodifiableListMixin` and `FixedLengthListMixin` are actually
	/// abstract classes, not mixins. They are both inside
