l.int()

Passes when the value is int. Returns an IntValidator, a NumberValidator<int, int?> with .min(), .max() and .finite(). On the VM, 42.0 is a double and fails. On the web every number is a JavaScript number, so 42.0 is int is true there. For JSON that may carry either form, use l.num().

Signature

NumberValidator<int, int?> int({String? message, MessageBuilder? messageBuilder})

Parameters

Parameter	Type	Meaning
message	String?	Replaces the default error message.
messageBuilder	MessageBuilder?	Builds the message from the issue. message wins when both are given. See Message builders.

Issue

Code invalidType. Default message: value must be an integer. value is replaced by the field name when there is one.

Code generation

An int parameter maps to l.int(). @HasMin(n) and @HasMax(n) add .min(n) and .max(n); a fractional n on an int field fails generation.

Example

Hand-written

final count = l.int();

Generated

@HasMin(18) required int age, // l.int().min(18).required()

count.validate(input)+1-2

1. +valid: 42
2. -invalid: 42.0value must be an integer
3. -invalid: '42'value must be an integer
