I wish you are my mentor sir
Thank you so much for your kind. Keep watching keep sharing.
@@abdurrehman6203 aslam o alikum sir how to read data from external file sqlite
Can you please show, how to keep the last item at the top? I tried shrinkWrap and reverse. It works when the list items are inside the page. But when the list grows, the newly created item stays behind the appBar.
you can reverse your array list not the listview builder and then it will sort the data. Or you can add time stamp and then fetch the data in ascending order using time stamp. Beside this set reverse == true in listview builder and wrap children with container and give it height like your card height is 20 then give it a height * your list length. I won't recommend this last method.
Future getNotesList() async {
var dbClient = await db;
final List queryResult = await dbClient!.query('notes');
return queryResult.map((e) => NotesModel.fromMap(e)).toList().reversed.toList();
}
Change the code in db_handler.dart file
Basically humne phle list bnaya fir usko reverse kr diya
There is a glitch in your code,let me explain
you declare id as nullable,so if somebody doesnot provide value of model class during insert method the id will be auto generated and when we will view there will be error 'String is not a subtype of null',So we have to check if any value is empty the id should not be auto generated,I dont know how to this at this time
I'm assuming you will not let user pass null values, this is just to make you understand concepts rest you can play with this
Everything is going above my head, I don't understand the Map thing, you could have explained this while creating map and db_ as I'm beginner and not understand a single word. But I really appreciate your effort and skill sharing brother
.
I agree sir I haven’t share the knowledge i was supposed to share. I am making this video private and will create new video
thank you very much sir this app is complete or have a part two that have a data from user
This is complete
pls provide github link of project in description, which you explain on youtube , so that is more use full for new learner of flutter.
Ok

I have a few questions.
How do I access this database file from outside with VSCode.
Can you elaborate your question, "outside with VSCode" ?
@@thetechbrotherss i have done a web and desktop project with c# and mssql. i also did a mobile project with flutter. I dec to make a connection between them.
@@thetechbrotherss i tried using mssql in flutter, but I got errors.
bhai kiya hum notes ko store kar sakte hai in mobile app yes than how ?
Jaise is lectured ma kia hain waise kr skty ha
In software houses ai calling and firebase is more demanded
Yes, you can say that. But this was just a simple tutorials to teach some basic concepts of SQL in flutter with example so you can use them according to your requirements like creating cart etc.
Assalam o Alikum ! when you make the notesModel.from contructer you decleared the Map.............but in body when you assighn the value to id it gives error because id is not type of string it is integer so brother make it correct and declear the type of map to object and dynamic
Thank you for sharing your knowledge sir
