Is it possible to declare a variable with the final modifier inside a method without initializing it immediately?

In the Dart language (used in Flutter), a variable with the final modifier inside a method can be declared without immediate initialization, but it must be initialized before its first use; otherwise, a compilation error will occur. This is possible thanks to lazy initialization, for example:

void example() {
  final int x; // declaration without initialization
  x = 10;      // initialization before use
  print(x);
}

However, once assigned, the value of a final variable cannot be changed. If you try to use the variable before initialization, the compiler will generate an error.
