[@crazyvolt1660]

Thank you, Im a student of Flutter, and this tutorial helped me a lot. :)

[@George-or3uv]

Excellent work. I cannot tell you how long that I have been waiting for a tutorial like this!

[@wissalmahdi1167]

Very helpful thanx a lot

[@speedtnt7591]

thank you but shall we use node.js? or we can make or models with just flutter and mongodb?

[@guilhermelincoln8574]

perfect my friend 🙏

[@shahanasheikh9814]

man you are making amazing tutorials! keep it up.... but the only problem is the big text on screen stays for a much longer time kindly keep it only for 2- 3 seconds. Thankyou again

[@DevMensIT]

Thanks. I will try ☺️

[@boneclinkz5663]

question, can i insert and store any media files such as mp4, collada,obj and svg?

[@DevMensIT]

For that you should use storage

[@bloomingtonsdirect6921]

why do we need to refresh the browser to display the data in collection?

[@DevMensIT]

Because it wasn't auto refreshed so i manually did that thing for new data.

[@BrentSancken]

Hey! I followed through to the Querying video and as part of the Update you added lines 25-32 with the ModalRoute to the insert.dart file and if I go back and try to display the MongoDbInsert() as my homepage after that point, it doesn't work. I assume because it's expecting data from the previous screen but since there is none, it's null. How would I fix this/ be able to have access to Inserting new records as well as updating/deleting them?
Exception is _CastError (type 'Null' is not a subtype of type 'MongoDbModel' in type cast)

[@DevMensIT]

sorry for my later reply...
just give MongoDbModel? data :)
if you will pass null it will work too

But when I refresh the MongoDb database
It shows NO RECORD FOUND

BTW when i debug, it says
"Launching lib\main.dart on Windows in debug mode...
Exception: Unable to find suitable Visual Studio toolchain. Please run `flutter doctor` for more details.

after insert, i get this in my terminal:

Hey @The Dev Man I got a quick question. Inside MongoDBModel.dart -> should "final mongoDbModal = mongoDbModalFromJson(jsonString);" be commented out or not?
