Thanks so much, I have got to understand very well. Besides, my post_list page showed the circular progress indicator and not the data. I tried catching the error, but it seems everything is working fine. What do you suggest?

Hi if you are still having the error, then check whether you are returning the appropriate widget from the builder function when data is available. Sorry for the delay in responding. Stay connected.

in the Post Details page, you passed "post" into EditPost page at 32.29 timeline, how did you identify it within that context? mine is showing unidentified post
@droidmonk4820 Жыл бұрын
Let me check
@droidmonk4820 Жыл бұрын
This is a valid confusion; I am sorry for that. Declare the "Map post" above the build function --- late Map post; @override Widget build(BuildContext context) {} Inside the builder function of the FutureBuilder , once you get the data assign it to the variable post if (snapshot.hasData) { post = snapshot.data!; .....} Take a look at relate source code on the link below: github.com/gitanjal/flutter_http_basics/blob/master/lib/screens/post_details.dart

i have an error _CastError (type '_InternalLinkedHashMap' is not a subtype of type 'List' in type cast)

Most probably you are getting this while trying to fetch the details of one post, right! (may be at snapshot.data). Meaning: You are trying to put an instance of Map in a List. Solution: Try changing the type of the variable(Where you want to put the result) to a map.

I am getting the error 'The method 'jasonDecode' isnt defined for the typre 'HTTPHelper'.
@droidmonk4820 Жыл бұрын
Add the line below at the top of the file containing the HTTPHelper class. import 'dart:convert'; The method jsonDecode belongs to the library dart:convert . Thus you must import the library to be able to access it.
@gregorybecker2231 Жыл бұрын
I fixed it... changed Import 'dart:convert' to Import "dart:convert' as cnv then changed items = cnv.jasonDecode(jasonString)
