Dart => expr syntax only an expression not a statement is partial

Question

Dart => expr syntax notes:

Only an expression—not a statement—can appear between the arrow (=>) and the semicolon (;).

case:

sayHello(String name) => print("Hello, $name");

Here I think print is a statement.

Generally we agree:

• Expression: which can be calculated as a value.
• Statement: a piece of code which can do logic processing.

=> can be understood as a single-line function, a expression or a single-line statement(Function Expression).

Answer 1

if ..., for ..., switch ..., would be statements. print() is a function call that evaluates to void and is an expression as a + b which is also a function call like a.operator+(b) just with a different syntax.
