✌ If you want to change color based on value #

The add a ValueColor object to valueColors, which is an array, you can add more ...,but always take the last eligible

int value = 9999; // or use Controller.value
AnimatedDigitWidget(
  value: value,
  textStyle: TextStyle(
    color: Colors.orange[200],
    fontSize: 30,
  ),
  valueColors: [
    ValueColor(
      //When value <= 0 , the color changes to red
      condition: () => value <= 0,
      color: Colors.red,
    ),
    // you can add more ...,but always take the last eligible.
  ],
),

🐳 Widget Params & Documentation #

🚀 Required Params

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

  • controller - digit controller, The displayed number can be controlled via addValue and resetValue.

  • value - the display number.

🍑 TextStyle And BoxStyle Setting

  • textStyle - the numbers text style.
  • boxDecoration - Use with decoration of Container.

🍇 Int Type(default) Or Decimal Type Setting

  • fractionDigits - the fraction digits, int, default 0.
    • 🖌 Example ( 1000520.98765 ):
    • 0 => 1000520;
    • 1 => 1000520.9;
    • 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)
  • separateSymbol - the numbers separator symbol (only enableSeparator is true), make numbers much easier to read, default ,.

    • 🖌 Example ( 1000520 ):
    • , => 1,000,520
    • ' => 1'000'520
    • - => 1-000-520
  • separateLength - the numbers separator length (only enableSeparator is true), separateSymbol by separator length insert, default 3.

  • curve - the animate curve, default Curves.easeInOut. look animate curve.
  • loop - enable loop scroll animate. default true, always scroll down, not scroll up from 9 -> 0; false, scroll up and down.

🍎 Digital Size Scheme Setting

  • autoSize - the default true is to automatically expand and contract according to the size of the ( number / symbol ) itself, false, the text size of the number 0 is used as the container size of each number, which can ensure the same width, but it seems that there is a slight interval between 1 and other numbers 😊 .

  • animateAutoSize - the animation resizing. default true, false will change directly to the size of the number/symbol.
