Flutter : FormatException: Unexpected character (at character 1) HTML

Issue

I’ve tried to insert my html text to display on my flutter apps, I’ve got some warning.
But the result was good.

My Code:

'''
final response = await http.get(
Uri.parse(BaseUrl.apiBaseUrl + 'myapi'),
headers: {HttpHeaders.authorizationHeader: "Bearer " + token});
      
final result = json.decode(response.body);
'''

How I fix this warning?
Result:
I/flutter ( 8104): FormatException: Unexpected character (at character 1)
I/flutter ( 8104):
I/flutter ( 8104): ^
I/flutter ( 8104): FormatException: Unexpected character (at character 1)
I/flutter ( 8104):
I/flutter ( 8104): ^

html flutter

Solution

The problem is on final result = json.decode(response.body);
In your response body, you are either getting a null or a non JSON format. That’s why when your code is decoding it into JSON there is an exception.
