I'm using this package Hive
In my code, I load json from firebase storage and store in Hive box at the beginning, and my web has very slow inital loading (4-5 seconds).
Does it come from Hive or not? Hive is integrate everywhere in my project, so removing it for test is not a good idea.

I am about to start a flutter project and coming from android kotlin I was looking for the closest database to room.
I have read about floor and hive.
Before spending hours using both to figure out which one to stick to, I was wondering what you suggest guys.
I don't want to use firebase since the data remain mainly on tve user's device.
If you are happy with room and Kotlin I'd say Floor is your best bet for Flutter. While I haven't used either, I have used other object mappers with SQLite as well as Hive.
Now Hive as non-SQL database is totally different from an SQL based database.
I am using hive for flutter application,
Is it safe, is it scalable, good to continue with hive or should I use sqlite or any other database for flutter application.
here are some features of hive :
Hive is a lightweight and blazing fast key-value database written in pure Dart.
have 120 points that is full a package can have.
As per flutter official policy no any package can be deleted once its uploaded on pud.dev.
Strongly encrypted using AES-256.
so you should definetly go for hive. if you don't have experience in native.
I am in the process of adding integration tests for my flutter app (Android & iOS).
I am planning on having a sort of BDD test structure, with the Given parts implemented as data that I want to load inside the database.
I am using the Firebase emulators to launch a local instance, following the production rules. However, I can see of no easy way to bypass the rules to populate the database before running the tests.
there is an import folder option from firebase emulator, but this would
decouple completely the data from the tests, making it very hard to adjust one without breaking the other
imply either a restart of the emulator between each test, or a database state containing many different cases, with each test using different parts of the data.
using the firebase sdk from the flutter code seemed ideal, however there's a flutter plugin that seems not maintained and pre null-safety, and no official option
manually creating the desired state from within the app with a logged-in user (or four) before performing the actual test (the slowest and less reliable way)
Am I missing something obvious? Is there a better option with the emulator to front-load data before a given test? A good way to manage this data? Thank you in advance!
I'm a beginner programmer on the dart and flutter. I want to create an app to manage my small shop and save data on a physical device. I searched for any code samples, but I couldn't find anything. Any ideas or suggestions from Flutter professionals to begin my project will be really helpful.
You can either use sharedPrefernce plugin for storing data. But data may be persisted to disk asynchronously, and there is no guarantee that writes will be persisted to disk after returning, so this plugin must not be used for storing critical data.
Another option is Hive fast key-value database written in pure Dart.
you can also explore other options like sqllite or firebase_database
flutter create appname - This can be used to create flutter app
How to sync data between MySQL server and Sqflite in flutter? I just want to integrate the offline mode in my flutter app...
Is there any library for this?
Unfortunately, there is no library for this. But, it should be pretty straight forward to implement. Just follow these 3 points:
1) Create a function for initial upload of data on SQFLite on from MySQL database when for eg: when a user enables offline mode, or logins for the first time, etc. whatever is relevant to your use case.
2) Then you have to have another function which when the user is online, checks if SQFLite data is in sync with MySQL, if not it updates SQFLite database (This step is unnecessary if the MySql database for the user can only be modified by the user, in which case just the 3rd point is sufficient)
3) Another function is required where when the user changes MySQL data(read, updated, deletes), SQFLite data is updated by recent MySQL data.
If you know basic querying of MySQL and SQFlite (which is quite similar) and are familiar with deserializing data, this should be easy to implement.
