Issue

Code tooBig. Default message: value must be less than or equal to 100. value is replaced by the field name when there is one.

Code generation

@HasMax(n) on an int, double or num field, with the same rules as @HasMin.

Example

Hand-written

final age = l.int().max(100);

Generated

@HasMax(100) required int age,       // l.int().max(100).required()
@HasMax(1.5) required double ratio,  // l.double().max(1.5).required()

age.validate(input)+1-1

1. +valid: 100
2. -invalid: 101value must be less than or equal to 100

final ratio = l.double().max(1.5);

ratio.validate(input)+1-1

1. +valid: 1.5
2. -invalid: 2.0value must be less than or equal to 1.5
