.min()

Passes when the value is at least minValue. The limit has the validator’s number type: int on l.int(), double on l.double(), num on l.num().

Signature

NumberValidator<N, O> min(N minValue, {String? message, MessageBuilder? messageBuilder})

Parameters

Parameter	Type	Meaning
minValue	N	The smallest accepted value, inclusive. params['min'].
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 tooSmall. Default message: value must be greater than or equal to 18, with the limit as given. value is replaced by the field name when there is one.

Code generation

@HasMin(n) on an int, double or num field. n is a num; a fractional value on an int field fails generation. On a String field the same annotation is a minimum length.

Example

Hand-written

final age = l.int().min(18);

Generated

@HasMin(18) required int age,       // l.int().min(18).required()
@HasMin(0.5) required double ratio, // l.double().min(0.5).required()
@HasMin(0) required num total,      // l.num().min(0).required()

age.validate(input)+1-1

1. +valid: 18
2. -invalid: 17value must be greater than or equal to 18

On a double validator the limit is a double:

final ratio = l.double().min(0.5);

ratio.validate(input)+1-1

1. +valid: 0.75
2. -invalid: 0.25value must be greater than or equal to 0.5
