RangeValidator<T extends num> class
A validator that checks if a numeric value falls within a specified range.
RangeValidator ensures values are between minimum and maximum bounds. Both bounds can be inclusive or exclusive depending on configuration.
Example:
RangeValidator<double>(
0.0,
100.0,
inclusive: true,
message: 'Must be between 0 and 100',
)
