isInExp method
An expression that evaluates to true if this expression resolves to a
value that one of the expressions resolve to as well.
For an "is in" comparison with values, use isIn.
Implementation
Expression<bool> isInExp(List<Expression<T>> expressions) {
if (expressions.isEmpty) {
return Literal(false);
}
return BinaryExpression(
this,
BinaryOperator.$in,
ExpressionTuple(expressions),
);
}
