print data form List of Maps flutter/-CodePudding

I need to print startTime form this Map of decodedData. I am new to flutter . I need startTime so that I can show the time slots for availability.

Map decodedData = { "sts" : "SUCCESS", "data" : [{
                    "slotKey": "1665392445000_|_1665394245000",
                    "startTime": 1665392445000,
                    "endTime": 1665394245000,
                    "isbooked": true,
                    "bookedBy": "qxWESdGsHvhywe3S7FxDeO2"
                  },
                  {
                    "slotKey": "1665414045000_|_1665415845000",
                    "startTime": 1665414045000,
                    "endTime": 1665415845000,
                    "isbooked": false
                  },
                ]};

Try this:

for(var item in decodedData["data"]){
    print("startTime = ${item["startTime"]}");
}

CodePudding user response：

You must try this :

 decodedData["data"]).values.forEach((v) => print("startTime = 
    ${v["startTime"]}"));

CodePudding user response：

You can use decodedData[0]['startTime'] and so on, you can also use for loop. and use
DateTime.fromMillisecondsSinceEpoch(decodedData[0]['startTime'],isUtc: true).toString() to print it or format it as per your need.

CodePudding user response：

 List<String> arrayStartTime = (decodedData["data"] as List<Map<String,dynamic>>).map((e) => "${e['startTime']}").toList();

result:

[1665392445000, 1665414045000]

You can set array int or String type as per your requirement

void main(){
  for(var item in decodedData["data"]){
    print("startTime = ${item["startTime"]}");
}
