|
| + * * A literal string where any interpolated expression is a compile-time

|
| + * * A constant constructor invocation.
|
| + * * A constant list literal.
|
| + * * A constant map literal.
|
| + * * A simple or qualified identifier denoting a top-level function or a static
|
| + * method.
|
| + * * A parenthesized expression `(e)` where `e` is a constant expression.
|
| + * * An expression of one of the forms `identical(e1, e2)`, `e1 == e2`,

| + * `e1 != e2` where `e1` and `e2` are constant expressions that evaluate to a
|
| + * numeric, string or boolean value or to `null`.
|
| + * * An expression of one of the forms `!e`, `e1 && e2` or `e1 || e2`, where
|
| + * `e`, `e1` and `e2` are constant expressions that evaluate to a boolean
|
| + * value or to `null`.
|
| + * * An expression of one of the forms `~e`, `e1 ^ e2`, `e1 & e2`, `e1 | e2`,
|
| + * `e1 >> e2` or `e1 << e2`, where `e`, `e1` and `e2` are constant expressions
|
| + * that evaluate to an integer value or to `null`.
