doubleStringWithoutTrailingZeros

dartCopy codeString doubleStringWithoutTrailingZeros(String? doubleString)

Given a number string, this function will display decimals only if it contains them. For example:

• 0.012 => 0.012
• 3.2 => 3.2
• 2.0 => 2

numberToRoundedValue

dartCopy codeString numberToRoundedValue(dynamic number, {String Function(dynamic)? orElse})

Given an object, this function will try to parse it as a double and round the value, returning a string. It also provides a fallback function [orElse] to use if the value processed is an invalid number. By default, this returns 0 if no fallback is provided.

formattedPrice

dartCopy codeString formattedPrice(double? price, [String? symbol])

Returns a string representing a formatted price with currency. A custom [symbol] can be provided to be used instead.

pairedListToMap

dartCopy codeMap pairedListToMap(List list)

Given an array of sequential paired items, this function will transform it into a map. For example:

• ["key1", "value1", "key2", "value2"] -> {"key1": "value1", "key2": "value2"}

mapToPairedList

dartCopy codeList mapToPairedList(Map map)

Given a map, this function will transform it into an array of sequential paired items. For example:

• {"key1": "value1", "key2": "value2"} -> ["key1", "value1", "key2", "value2"]

modifyPairedListAsMap

dartCopy codeList modifyPairedListAsMap(
    List list, Map Function(Map) transformer)

This function lets you modify an array of sequential paired items as a map and return it in the array form. Check [pairedListToMap] for more details.
