This charset mangling is called Mojibake (Thanks Randal Schwartz for pointing out!)

You cannot change "Déjà Vu" back to "Déjà Vu", you have to take action on either the way data is encoded and sent or the way you decode the response.

See the binary representation of these utf-8 characters:

It seems there is an internal optimization to do this. They use Uint8List so there isn't wasted memory like you said.

You don't unsubscribe from Stream. You unsubscribe from StreamSubscription using the cancel() method.

So first start listening to your stream using .listen() on the stream, this will return you StreamSubscription which you can then cancel.

You have:

The Dart SDK does not really handle different timezones which is the reason why the parse want local timezone (which is the timezone on the system running the program) or UTC.

If you are trying to parse a timestamp without any timezone information, Dart will assume the time are in local timezone (I am in Denmark which are using the Romance Standard Timezone):

Writing the constructor like this effectively makes the class final (Classes are unable to extend from this class). Only generative constructors can be used to call super(). This is as opposed to factory constructors which cannot be used in such a way. As the only generative constructor is the private one named _, extension is prevented. There is the caveat that classes in the same package could extend the class as private members are available to classes in the same package.

By having the factory constructor, instances of MapEntry can still be created even though the default constructor is private.

The issue is with the user settings, how the end-user has set the scrolling to happen with his mouse. I have a Logitech mouse that allows me to turn on or off the smooth scrolling capability via Logitech Options. When I enable smooth scrolling it works perfectly and scrolls as required but in case of disabling the smooth scroll it gets disabled on the project as well. The behavior is as set by the end-user.

Still, if there's a requirement to force the scroll to smooth scroll than can only be done by setting relevant animations. There's no direct way as of now.

The Dart 2.2 language specification says:

One may well ask what is the motivation for introducing literal symbols? In some languages, symbols are canonicalized whereas strings are not. However literal strings are already canonicalized in Dart. Symbols are slightly easier to type compared to strings and their use can become strangely addictive, but this is not nearly sufficient justification for adding a literal form to the language. The primary motivation is related to the use of reflection and a web specific practice known as minification.

Minification compresses identifiers consistently throughout a program in order to reduce download size. This practice poses difficulties for reflective programs that refer to program declarations via strings. A string will refer to an identifier in the source, but the identifier will no longer be used in the minified code, and reflective code using these would fail. Therefore, Dart reflection uses symbols objects of type Symbol rather than strings. Instances of Symbol are guaranteed to be stable with respect to minification. Providing a literal form for symbols makes reflective code easier to read and write. The fact that symbols are easy to type and can often act as convenient substitutes for enums are secondary benefits.
