title: How to parse json in dart
body: <p>I am receiving json string through an API from a website. However, the json format sent to me is not the format i want to work with. I want to change the received json string format to the desirable format.</p>
  
  <p>This is the format i received:</p>
  
  <blockquote>
    <p>{"symbols_returned":147,"base":"USD","data":{"AED":
    3.673010,"AFN":75.392000,"ALL":109.685000}}</p>
  </blockquote>
  
  <p>This however is the format i desire to have:</p>
  
  <blockquote>
    <p>{"symbols_returned":147,"base":"USD","data":{"AED":"3.673010","AFN":"75.392000","ALL":"109.685000"}}</p>
  </blockquote>
  
  <p>The difference between the former and latter is the presence of quotation marks on all the numeric currency values in the second json string. It can be seen that the first json string does not have quotes on the numeric currency values.</p>
  
  <p>My question is how can i programmatically turn the first json string to the second json string format using dart programming language. Any help will be appreciated. Thanks</p>
