This helps me so much for learning flutter. I already started to learn flutter 2-4 months ago and now I am exercising code and saw this video. IT'S FKING AWSOMEEE WİTH EXPLANATİONS. Keep going dude.
At the start it was nice and calm fetching apis are pretty clear but dont know what are u doing with json continuesly creating classes and factory constructor :(
Hello! First of all thanks for the video, it helped me to understand better flutter and how the widgets work. I have a question, I followed your instruction to get the name of the city, but from the logs and the terminal it prints the error: "Error: Unexpected null value." I even tried to print the list but same results. But the API (I used the same as yours) is correctly returning the latitude and the longitude. Any advice or solution?
Thank you very much for the tutorial! but why is it that when I run the project it always fails and points to the getAddress line at file header_widget.dart an there is no error description. I try to run your source code but it has the same problem. How can I fix that problem? I have no idea.
Fantastic video!!! It helped me so much. Is there a way to update the data every 10-15 minutes maybe using a timer or something else? Last thing, maybe a video with permissions request with dialog when it they are refused (like android rationale) can be nice (using permissions_handler, app_settings or similar)
First of all thank you so much for being the part of our Patreon community. I was super happy to see you supporting the channel and those small contributions help in growth of this channel. I will be adding a last updated and reload button to the app where we can reload and get the data. Also for the request dialog, will see the packages that I can use
Sorry i just forgot about that. I am sharing my whatsapp number with you on patreon message chat. We can disucss more on the weather app features on whatsapp
At 44:24, You added a city = place.locality!; and then you restart the app and it shows you location ..... but in my case when i reload my app, it pop-ups 2 tab in vs-code that are binding.dart and plugin_registry.dart. In binding.dart, on line no. 359, it says "completer.complete(reply);" where the text cursor blinks between completer and (.) & in plugin_registry, on line no. 126, it says " callback(response);" where the cursor blinks in front of callback. What is the problem ? I am confused why i am getting these pop-ups while i debug.
Hi thanks for awesome tutorial! I got an error "latitude is out of range of [-90.000000, 90.000000] (too low)" and don't know how to fix it. can anyone help me?
awesome tutorial. Thanks a lot. but my initState() function for getting the placemark is called before the globallController retrive the location data data. the placemark function is not waiting for the Globalcontroller to load. how to solve this
what if the location service is not enabled in mobile device.It Keeps on going circular progess indicator and error shows on the debug console on pc.Is there not the way to make popup on the app showing that location service is not enabled in the device?
Is this possible in flutter which can download the video from server and store it in SD card. and plays it while the app is in offline mode. Like UA-cam download function???
Hii ,great tutorial. Please I got this error : this supplied phased action failed with an exception. Could not open knit generic class cache for initialisation script
i didn't get any video for flutter notification with action buttons. like to decline or accept call, mark as read or reply button. can you make a tutorial on this please?
Hello I'm very grateful to you and your video which is super awsome . I have a question at while the first run of the project to test the API call an exception happened Exception has occurred. _CastError (Null check operator used on a null value) with the code import 'package:weatherapp_starter_project/model/weather/weather_data_current.dart'; class WeatherData { final WeatherDataCurrent? current; WeatherData([ this.current, ]); WeatherDataCurrent getCuurentWeather() => current!; and it couldn't run could you please help
can you please check if you are storing data to weather data current class. If you think issue exists then you can go to our pateron membership page and clone the source code for weather app. Thanks
I am getting an Exception Error: "Exception has occurred. _TypeError (type 'String' is not a subtype of type 'int')" For this Code: String getTime(final timeStamp) { DateTime time = DateTime.fromMillisecondsSinceEpoch(timeStamp * 1000); String x = DateFormat('jm').format(time); return x; } pls help!
the place where you are calling getTime, and passing timestamp value. I guess timestamp is string in your case. try to wrap it with int.parse(). So it will be like getTime(int.parse(time))
I mean the source code is available for patreon users, so you can check the source code there mate. Also, joining our channel as Patreon would be good for you also❤️🫠

I encountered the same issue and had to debug a bit to identify its origin and understand what I was doing wrong. The solution, at least for me, was to: Verify the API call and ensure its correctness, which was not the case; there was a missing attribute in the API link, leading to the error (the API returned a 401 unauthorized error, causing a null error). After correcting the link, it worked as expected.
You have made it very complicated by making weatherdata everywhere..weather data, current weatherdata, weatherdata current, currently data weather, weatherly data current..etc. Making classes and files of identical names makes it super confusing... And you named dart Generated class as Weather which is again included in Json response.. So you got a weird weather class on 54:15 which is the main JSON parsed class
thanks for your suggestion. I knew this was something that was done a long time ago, hopefully if community need weather application videos, then will create some good code for it
