every thing covered in these video sqlite queries,lists,fetching from list , mapping , modular ui using methods 1000 of like from my side .. Thank you vipin
By the way, I want to also thank you for all the personal support on my project following your other video on JSON Models. I appreciate the effort. It made life easy
Thank you so much for this tutorial. I have been looking for a straight to the point approach like this. Very helpful. Thanks & Looking forward to more of your great tutorials from you.
It's a nice tutorial. But, it seems to me that. there are little dissimilarities between repo and youtube. And, you went fast in the last moment of the video especially form . Please update the repo.
Hello, thanks for the concise tutorial. is there a way to only update a single column of a particular row rather than updating with employee row again as shown in the video? If possible , can you share a query sample. Thanks!
@@MobileProgrammer G'day! I just meant to ask for updating just a single column like the traditional sql query way. E.g: Update the email address column of employee A with xyz@abc.com. I guess here we pass the employee map again which updates the entire row..Thank you.
i got an exception while pessing "ADD" ═ Exception caught by gesture ═══════════════════════════════════════════ The method 'save' was called on null. Receiver: null Tried calling: save(Instance of 'Employee') ════════════════════════════════════════════════════════════════════════════════
thank u for this video but i am a beginner in flutter and this error had done with me The following assertion was thrown building FutureBuilder(dirty, state: I/flutter (10456): _FutureBuilderState#52f11): I/flutter (10456): type 'MappedListIterable' is not a subtype of type 'List'
this is how initDb() function looks like initDb() async { // Get the Device's Documents directory to store the Offline Database... io.Directory documentsDirectory = await getApplicationDocumentsDirectory(); String path = join(documentsDirectory.path, DB_NAME); var db = await openDatabase(path, version: 1, onCreate: _onCreate); return db; }

hello i faced an issue and i am unable to fix it. when i press add button after pasing the name . it is showing an error in dataTable saying data!=null. i used print function to check whether the snapshot was empty or not but i found out it has data.so why i have this error. help me
@@MobileProgrammer Yea, that was the missing part but now my code stops during execution because of mediaquery being called in a media query without context
When I try to do this, it complains because getEmployee() returns a future, and I'm using it as a List in DbTestPage. I'm new to futures. Any idea what I am doing wrong, here?
I just thought perhaps there was a way to do it without then, as your code doesn't use it. Even your code exactly doesn't work as is. Likely this is just because your example is from a year ago, and I'm using a newer version of Flutter/Dart. Thank you for your help.
in file dbHelper.dart, at 4mn29sec, when I write "execute", it says that he methode "execute "is not defined in class "Future", I don't find any help in google...what can I do ? Tx
