Convert future string to string flutter

In order to convert a future value to a string in Flutter, you need to use the `async` and `await` keywords to handle asynchronous operations. Here is an example of how you can achieve this:

    
      Future<String> fetchData() async {
        await Future.delayed(Duration(seconds: 2));
        return 'Data Retrieved';
      }
      
      void main() async {
        String result = await fetchData();
        print(result);
        // Output: Data Retrieved
      }
    
  

In the above example, we have a function `fetchData()` that returns a `Future`. Inside this function, we are using `await` to wait for 2 seconds before returning the string ‘Data Retrieved’. Then, in the `main()` function, we are using `await` again to wait for the `fetchData()` to complete and assign the returned value to the `result` variable.

Once you have obtained the desired value from the future, you can easily convert it to a string using the `toString()` method. Here is an updated example:

    
      Future<String> fetchData() async {
        await Future.delayed(Duration(seconds: 2));
        return 'Data Retrieved';
      }
      
      void main() async {
        String result = await fetchData();
        String convertedResult = result.toString();
        print(convertedResult);
        // Output: Data Retrieved
      }
    
  

In this updated example, we have added a new variable `convertedResult` which holds the converted string value of `result` using the `toString()` method. The `print()` statement then prints the converted result.
