converting string to map in dart

Question

I wanted to convert a string to map.

String value = "{first_name : fname,last_name : lname,gender : male, location : { state : state, country : country, place : place} }" 

into

Map = { first_name : fname, last_name : lname, gender : male, location = {   state : state,    country : country,    place : place  } } 

How do I convert the string into a map<String, dynamic> where the value consists of string, int, object, and boolean?

I wanted to save the string to a file and obtain the data from the file.

Answer 1

That's not possible.

If you can change the string to valid JSON, you can use

import 'dart:convert'; ... Map valueMap = json.decode(value); // or Map valueMap = jsonDecode(value); 

The string would need to look like

{"first_name" : "fname","last_name" : "lname","gender" : "male", "location" : { "state" : "state", "country" : "country", "place" : "place"} }

You would have to change the way you create the string.

I'm guessing you are creating the string using the yourMap.toString() method. You should rather use json.encode(yourMap), which converts your map to valid JSON, which you can the parse with json.decode(yourString).
