What is const in flutter? The const keyword isused when the value of the variable is known at compile-time and never changes. In other words, the compiler knows in advance what value is to be stored in that variable. ... Flutter also automatically deduces the type of the variable when ...
If Flutter can call the build() method every frame, we should be careful about what we put inside it. But what is a side effect exactly? What is a side effect? Here's a good definition from Wikipedia): In computer science, an operation, function or expression is said to have a side...
If you define a constructor yourself, it is considered non-trivial, even if it doesn't do anything, so a trivial constructor must be implicitly defined by the compiler. In order for a special member function to satisfy the above requirements, the class must have a very simplistic structure, ...
in Flutter rows, columns, padding, and even the application itself are also classed as widgets, which is why our application class extends from something called StatelessWidget.

The best mnemonic I found for this is "new is glue": Every time you use new in your code, that code is tied down to that specific implementation. If you repeatedly use new in constructors, you will create a chain of specific implementations. And because you can't "have" an instance ...
