NumberFormat.percent constructor

NumberFormat.percent({ Locale? locale, SignDisplay signDisplay = SignDisplay.auto, Notation notation = const StandardNotation(), Grouping useGrouping = Grouping.auto, NumberingSystem? numberingSystem, RoundingMode roundingMode = RoundingMode.halfExpand, TrailingZeroDisplay trailingZeroDisplay = TrailingZeroDisplay.auto, int minimumIntegerDigits = 1, Digits? digits, })

Creates a NumberFormat instance for percent formatting.

WARNING: Not implemented on native yet.

• locale: The locale to use for formatting. Defaults to the system locale.
• signDisplay: When to display the sign for the number. Defaults to SignDisplay.auto.
• notation: The notation system to use. Defaults to StandardNotation.
• useGrouping: Whether to use grouping separators. Defaults to Grouping.auto.
• numberingSystem: The numbering system to use (e.g., 'latn', 'arab').
• roundingMode: The rounding strategy to use. Defaults to RoundingMode.halfExpand.
• trailingZeroDisplay: When to display trailing zeros. Defaults to TrailingZeroDisplay.auto.
• minimumIntegerDigits: The minimum number of integer digits to use. Defaults to 1.
• digits: Specifies the minimum and maximum number of fraction or significant digits.

Example:

import 'package:intl4x/number_format.dart';

void main() {
  print(NumberFormat.percent().format(0.5)); // Prints '50%'
}
