I am a beginner in flutter how do i convert list of string into int. Below is the example code

var data="18:00";
List<String> dataList = data.split(':');
print(datalist[0]);
print(datalist[1]);

Output will be 18 and 00 under 18, so how do i get this 18 and 00 in int type.

Answer 1

您可以通过映射每个元素并解析为int将String列表转换为int列表。

  List<int> dataListAsInt = dataList.map((data) => int.parse(data)).toList();

Answer 2

you can do this like:

var data="18:00";
List<String> dataList = data.split(':');    
for(String s in datalist){
  int a=int.parse(s);
  print(a);
}

hope this will help you

Just parse your data with int.parse(//your data)
