outstanding explanation man,thanks
thank you very much, very easy to understand, hope you will make more videos
thank you so much !
I learned how to build my app with sqflite from this tutorial
Glad it was helpful, @codinglife-ii1vr 😀
Just a tip, inside the _initDB method you can just use:
Insted of:
final dbPath = await getDatabasesPath();
final path = join(dbPath, filePath);
You can put:
Future _initDB(String filePath) async {
return await openDatabase(filePath, version: 1);
}
because openDatabase first parameter now gets the defaul database path automatically, just pass the database name "notes.db"
@@HeyFlutter You are welcome, sexy voice.
how we find the our db path where is this located
Great tutorial, thank you
Thank you Johannes :)
Thank you so much. So beautiful

My flutter teacher is you sir
I followed your instructions for my own use case, but was wondering how you would go about with multiple tables, i assume you would create a separate db.dart in which you initialise the connection, and create the tables from, but i can't figure out how to make that work.
Thank you so much Mr. J. Milke for uploading such a wonderful video in a fabulous manner. i found it very helpful.
Could u please share the code in pdf or word.
Thanks.
Johannes one thing that I'd like to know is how do you organize your code when you will have lots of different tables with different coluns and data, like storing lots of different models, using one db for it, I think we would need a helper to class that could do a CRUD in multiple tables/colums, maybe different db's too.
Hi, thanks for the code and the very clear walkthrough. Very well created. However I have a question for the insert statement. from 11:20 to 12:20. I understand that id is not generated from dart, so the id is auto-generated from db side. But why do we have to collect id after inserting to db?
We need to read, delete, edit, etc. items. How you will identificate single item to operate with it? We have probability to have items with same title.
Future delete(int id) async {
final db = await instance.database;
return db.delete(
_tableName,
where: '${TaskFields.id} = ?',
whereArgs: [id],
);
}
Thank you for your efforts, can i ask where can i find the file notes.db in my folder's app?
At 8:19 what must you put after onUpgrade: ? (after the colon: ) if you add new fields to your Create Table
Thank You Jonathan Munday! Follow this link: stackoverflow.com/questions/63347032/how-do-you-upgrade-a-flutter-app-with-sqlite-database
I hope you will get your answer 🙂
Thank you! Is the updating for "isImportant" working? When I try to update the "isImportant" of an already created note, it doesn't update.. I can't figure out how to fix it.. :(
Ty, it really help me so much!
Following the note model, how can add ManyToMany relationship with other table?
Thank You Alan Gómez! Follow this link: www.back4app.com/docs/flutter/parse-sdk/data-objects/flutter-many-to-many-relationship

Great video man! . Can you make a video about how to retrieve data from firestore and save it in a CSV file?
Thanks, Juan David! 🙂 Check out my videos about Firestore here. Instead of CSV File you could also use JSON files

Maa syaa allah tabaarakallah
is it possible using sqflite to create database such as for example we have user form with dropdown menu animals and birds. If user selects animals, all input textfields only related to animals should display and store the animals related info in animals table separately and viceversa for birds..input textfields only related to birds should store in separate table. but both the birds and animals list should be accesible from home screen.
Thank you for the perfect tutorial. I have a question, what if I want to have a list of initial data, so that anyone who download this app will have these data already stored in the app?
Don't know if it's the correct approach. But I just called create method inside the _CreateDB after creating the table.
Thanks for the tutorial.
You'll have to write a lot of code in flutter for SQL than C#.
Yeah, @achieverstv8244 🙂
thank you Johannes
also are need explanation on how to connect flutter app with firebase
Thank you 😊, innocent philbert! Check out this playlist on flutter and firebase : ruclips.net/video/Z0jFkP0A3B0/видео.html
nice one
@@HeyFlutter you can't believe i have listened to this video for more than 7 times, it's very interesting and has helped me a lot in my final year project, thank you man
Thank you, you are god!
Hey Johannes. Thank you for making this video. This is a perfect tutorial for sqlite. But I'm still confused what is the used of isImportant and number in the database?
Enrico you mean why was used number instead of the bool value? If so its because sql cannot handle bool values so we can control it by using number, false = 0 and true = 1, like on/off
thank you very much for the video, I wanted to know if it is possible to send an icon to the database and then display it in a widget for example, if so how to do?

Hi Johannes, thank you for another great tutorial. I have managed to write all the code for the db with all my relevant fields but I don't want to use it for a 'note app' I need to make my db work for a 'medications list'. I want the user to be able to list all their meds etc and then retrieve/update/delete from more of a form field type UI. Could you please give me some ideas on how to develop the screen so this would work with my newly created db?
I hope this makes sense, I am very new to coding and this is my first app!
Kind regards
Jane
Thanks, Jane Maddison! 🙂 Simply start with something more simple as your first app. This should be your first app: ruclips.net/video/UPSsxGQRIzs/видео.html
hello dear,
Can you explain in video how use search on data with sqf 🌻
@@HeyFlutter thanks 💜
Awesome! As always...
Hi, @Johannes Milke I wonder how to implement "saving data from internet/web-service to this kind of local database" to work like WhatsApp or Telegram. Any idea? or Do you plan to make tutorial about that thing?
Terima kasih atas balasannya, @@HeyFlutter...
That was great answer!
But, it will be hard for me, since I'm still newbie... anyway, thanks a lot
Thanks, Trik! 🙂 Simply download the files / data first and then store it your database such as learned in this of this tutorial. Learn more about loading data from the internet here: ruclips.net/video/Rlf5q2EGHzc/видео.html
Hi, I am currently learning flutter and Dart, Just have a little question. Why do we need to pass the value of "id" from INSERT method into the "Note" object using the COPY method?
Thank You Justin Dela Rapa! Follow this link: stackoverflow.com/questions/59967096/add-id-or-name-property-or-other-means-of-identification-for-flutter-web-applica
I hope you will get your answer 🙂
I have the same question actually
thanks a lot for the video sir. I want to ask if the Copy function is really needed in the Create function? can I change the return type of the Create function from Note to just void?
Thank you, Fathin Al Ghifari! 🙂. Then it will not work.
@@HeyFlutter what if replace the copy method with setter for ID field ? Idk why we need to copy all fields if we change only one.
Thanks, Johannes, for your work!
did you do this in null safety version ?
can you pleasemake a video on how to add and use excel in flutter .
Thanks again for the tutorial! I've noticed that after following your instructions, it works perfectly on iOS devices, but for some reason, on Android, the connection to the database is intermittently lost, when you leave the screen and return to it etc, such that even if you managed to store something in it, you can't see it. Is there any reason why this might be, on Android only (still working perfectly on iOS?
@@HeyFlutter You're welcome! Honestly, they are second to none. There was no error but I have actually managed to resolve it. Basically, I have tabbed sections on the app screen. Each section has its own sqflite table/database. What I had done was to have a separate database for each, each with its own table. I think that was the issue, when switching between tabs. Why might that be? Instead, what I have done is create a new database, with multiple tables. With just the one database, with tables for each tab, it seems to be working fine now :)
try putting the dispose method in a different file, i had this same issue so i solved it by moving it the the logout button of my app so the db connection was lost when logout was pressed.
Hi do you have tutorials flutter dart using sqlite for email login page? In which for login they read data from database
Hey 😊, @adilahusin! Check out this video: ruclips.net/video/-32HIsRf26o/видео.html I hope it may help you
