FrequencyTracker #
A utility tool to keep track of frequency of an item in a list. Can be used to keep track most frequently / least frequently added items.
Usage:
-
Install the package. Add to pubspec.yaml
- prismutils: 0.0.1;
-
Import the package
- import 'package:prismutils/prismutils.dart';
-
Create reference point, requires two parameters -- List of identifiers and List of items
List<String> identifier = ['name', 'defValue']; FrequencyGenerator fr = new FrequencyGenerator(identifier, itemList);
- Identifier List contains the parameters of nesting in your model, if any
-
Available methods:
-
registerItem(dynamic item) // Takes an item as parameter
- Add new item to the frequency list. If item already exists, updates the count of the item. Else, adds it to the list
Ex: fr.registerItem(itemList[itemList.length - 1]);
-
getFrequencyByValue(dynamic value) // Takes a parameter value
- Get frequency of a particular item in the sorted list. Returns back an integer value, corresponding to the frequency of the item in the list
Ex: int frequency = fr.getFrequencyByValue(itemList[0]);
-
getSortedList(bool reverse) // Takes a boolean parameter
- Returns back the list, sorted based on preference. True indicates descending sort, false indicates ascending.
Ex: List sr = fr.getSortedList(false); sr.forEach((element) { print('${element['name']['defValue']} - ${element['freq']}')
