have this String "name=jack&age=22&true&red" and i want to get all the value as sperate String i can get the first value by this but don't know how to get the other
String text = "name=jack&age=22&true&red" ;
var splitText = text.split("&") ; // [name=jack, age=22, true, red]
var firstValue= splitText.first ; // name=jack
By index:
splitText[1] // age=22
splitText[2] // true
splitText[3] // red
If you want to get what is after the equal sign as a whole chunk (the value of the key 'name' is jack) you can use this code:
void main() {
String text = "name=jack&age=22&true&red" ;
// This regex matches any alphanumeric followed by a '=' and those preceded by a '&'.
RegExp exp = new RegExp("&([A-Za-z0-9]*=)|([A-Za-z0-9]*=)");
final splitted = text.split(exp);
splitted.removeWhere((item)=> item.isEmpty);
print(splitter); // Outputs: [jack, 22&true&red]
}
I'm not sure whether this could be an answer. Why don't you try to use an index?
splitText[1] // age=22
splitText[2] // true
..
This looks a lot like query parameters from a Uri. If so, run this in dartpad to see an easy way to do this:
void main() {
var u = Uri(query: 'name=jack&age=22&true&red');
var qp = u.queryParametersAll;
print(qp);
}
Output:
{name: [jack], age: [22], true: [], red: []}
