What's the best way to sort MAP<String, Object> by value in Dart programming? - list

Question

I'm new to dart programming, I came from a Javascript environment
everything is fresh to me and I really have no Idea how this sorting works
in dart.
Here's an example from my API
List example = [
{"id": "1", "age": "20"},
{"id": "2", "age": "21"},
{"id": "3", "age": "22"},
]
Before I will assign "example" to other variables eg.
var example2 = example;
I want to sort it by "age", I found libs and other "LONG" solutions out there but feels like there's another way.. Thanks in advance!

Answer 1

There is sort function for list. Try reading the documentation a bit:
void main() {
List example = [
{"id": "1", "age": "20"},
{"id": "2", "age": "19"},
{"id": "3", "age": "22"},
{"id": "4", "age": "9"},
];
print(example);
example.sort((x,y) => x["age"].compareTo(y["age"]));
print(example);
}
EDIT: Your definition should contain integers logically:
void main() {
List example = [
{"id": 1, "age": 20},
{"id": 2, "age": 19},
{"id": 3, "age": 22},
{"id": 4, "age": 9},
];
print(example);
example.sort((x,y) => x["age"].compareTo(y["age"]));
print(example);
}
