After watching lots of video about hive I can say that this is one of the best and thank you Johannes. Only thing that you can add is how to use asset hive database which is quite rare scenario.

Yup ! I ran into a problem and now I think I see why we need the Type Adapters ... Correct me if I'm wrong, but that's to help us save different Model types directly?
Great video with easy to understand explanation. But the sample app fails to work when closed and reopened; throws the error "LateInitializationError: Field 'amount' has not been initialized." on (package:hive_database_example/page/transaction_page.dart:59:43). Except for this, it is a great tutorial to get a kick-start on Hive !!!
@@HeyFlutter Hi Johannes. Thanks for the tut. After changing with ? Im getting "The argument type 'double?' can't be assigned to the parameter type 'num'." in transaction page. so adding "!" variable names causing different errors. Could you help ? Thanks.
@@HeyFlutter Got it running once, and debugged the heck out of my flutter versions until I found that comment. All those late vars fail at some point. Making them nullable is no solution, since there are follow up errors when using the vars. Not easy to fix, if you are not proficient with null-safety (I come from pre 2.0 flutter). It would be very nice to provide a fix on github, since this tutorial seems to be good. Sind doch bloß 10min für dich ;-)

Good question, Helvecio Borges! 🙂 There are multiple scenarios - In case internet is not connected and still you wanna show some data - Loading from local is way faster then loading from cloud so in case there is some repetition of loading data you can store it locally - In case you just want to make a application with no need of cloud other than storing data. You can use local DB - and many more
Hey my question is do I need to ask for permission from user something like internal storage permission etc, or I can simply use it without permission as it is and in what file format it stores your data and where 🙄🙄 please help me out
@@HeyFlutter does this package will do those things automatically?? Or I need to write some code btw thanku so much ❤️❤️❤️❤️ you're doing fabulous work and also helping beginners like me 👍
Thank you, old men! 🙂 Well you are write we have to provide storage permissions. Hive makes use of storage path to store data in a particular directory. You need not to provide permissions explicitly you can make use of this package : pub.dev/packages/path_provider to access storage path as well as requesting permission

Where are we defining the box name ?
Hi Johannes, awesome work! Thank you for your great content! I'm on a project right now and looking for a possibility to add data to only one field of a Box with seven fields. Is that Possible? Hive is really great to use but this is something I stuck with... Is there any solution for it? I'm really looking forward to your answer. Greetings from Germany :)

So i have the question. ua-cam.com/video/w8cZKm9s228/v-deo.html you have function type 'Future', but func returns nothing. My IDE starts to swear at me at theat moment. How do yo make it happen? If you write type of function you must return that type in function body. Isnt it?
Thanks, Собака Собака! 🙂 Learn more about it here: flutteragency.com/how-to-use-future-return-value-as-if-variable-in-flutter/
@@HeyFlutter ahah, thanks for answer, at that moment im junior developer at work. Not actual question.
Bro please SEMBAST too!
fantastic tutorial as usual, but in all honesty i feel this is sooo much coding for a DB that's neck to neck with Shared Preferences, Sure Hive has an advantage but still...
my build runner command doesnt show any output

@@HeyFlutter ya got the error thanks
The creator of hive is now making isar, much more promissing.
Still in alpha version though.
Thanks, jousis! 🙂 Yep, you are right, this is also interesting. Let's wait until it becomes more stable.
why late keyword is used here ?
Thank you, Pradeep Kumar Reddy Kondreddy! 🙂 when we are not initializing a variable then we usually use late keyword to avoid build time errors
amazing
super convenient
flutter packages pub run build_runner build, thank me later
Subbed

Great, Thank You Senpo
