JsonNumber class

A specialized JSON field for handling generic numeric values.

JsonNumber extends JsonField<num> to provide type-safe handling of numeric values that can be either integers or doubles. It's useful when you need to accept any numeric type without specifying whether it's an integer or floating-point number.

Key Features:

• Accepts both int and double values (via num type)
• Parses numeric strings to numbers
• Defaults to 0 when value is null
• Type-safe numeric operations

Usage Example:

final count = JsonNumber('count');
count.value = 42;        // Integer
count.value = 3.14;      // Double
count.value = "100";     // String parsed to number
print(count.value);      // 100
