Flutter/Dart - Split Comma Separated String into 3 Variables?
You could use a Map, which is better suited for variables with dynamic length :
final tagName = 'grubs, sheep';final split = tagName.split(',');final Map<int, String> values = { for (int i = 0; i < split.length; i++) i: split[i]};print(values); // {0: grubs, 1: sheep}final value1 = values[0];final value2 = values[1];final value3 = values[2];print(value1); // grubsprint(value2); // sheepprint(value3); // null
If you want just want to check if tagname is null just use tagname?.split(). But then when you get the values you will have to do this as well because otherwise you'll get a null exception splitTag?[] ?? "" The ?? is optional if you want to return a blank string instead of null.
you can use a list and add items one by one
final names= 'first, second';final splitNames= names.split(',');List splitList; for (int i = 0; i < split.length; i++){ splitList.add(splitNames[i]);}
