How to join maps from List of Maps in Flutter? - flutter

Question

I have this List:
var listMap = [
{
"type": "Spouse",
"name": "Mother",
"age": 50
},
{
"type": "Family",
"name": "Lili",
"age": 16
},
];
var finalResult = [
"type": "Spouse",
"name": "Mother",
"age": 50,
"type": "Family",
"name": "Lili",
"age": 16, ];
How can i achieve finalResult?

Answer 1

List<Map<String,dynamic>> listMap = [
{
"type": "Spouse",
"name": "Mother",
"age": 50
},
{
"type": "Family",
"name": "Lili",
"age": 16
},
];
try to loop them and add them 1 by 1
for(var x in listMap){
for(var y in x.entries){
newList.add("${jsonEncode(y.key)}:${jsonEncode(y.value)}");
}
}
// or use print
log(newList.toList().toString());
result
["type":"Spouse", "name":"Mother", "age":50, "type":"Family", "name":"Lili", "age":16]
you can try this to dart pad.
