🐳 Widget Params & Documentation #
🚀 Required Params

⚠️ value and controller cannot be both null.
⚠️ controller has higher priority.

value - the display number.

🍑 TextStyle And BoxStyle Setting

textStyle - the numbers text style.

2 => 1000520.98;
3 => 1000520.987;
N => 1000520.[N];

The default 0 means an integer, when it is a decimal, if the value is less than the fractionDigits, it will be filled with 0 to the right, and the truncation method is used, so there is no rounding.

🍓 Numbers Free Style Setting

decimalSeparator - the decimal separator，can be replaced by other symbols in place of decimal separators, default ..

enableSeparator - enable digit separator. default false not enable, only true, separateLength and separateSymbol valid.

🖌 Example (true): 1000520 => 1,000,520 (seealso separateLength or separateSymbol)
