I'm trying to implement this functionality in Flutter. The android side is easy to mimic using the android_intent package, however I've yet to find a way of launching custom URL schemes in Flutter. There are packages that allow custom URL schemes to be accepted in the app, however I don't think they can be used in my case (uni_links).
I'm aware that I could use platform channels however I would prefer to keep my code all in Dart. Thanks
I use firebase_dynamic_links to handle custom URL schemes. You may want to consider also looking into that. You won't be needing to touch platform-specific code, but you'll need to update the AndroidManifest.xml and Info.plist file.

How can I access device information without using packages in Flutter? How can I get the information of the device where the app is installed in my Flutter app?
First, you'd be better off using packages. But if you really want/need to do it, you'd have to write platform-specific code code in the native language of the targeted platform (ie. Swift or Objective-C for iOS/Mac, Kotlin or Java for Android, etc), then use so-called platform channels to pass messages between your app and the platform-specific code.
If you'd like to get details about the device, on iOS you'd use UIDevice, on Android you'd typically want Build.
This can only be done through Method Channel
I would like to add plugins like camera, scanner in an react-native-app but this involves addition of some additional code into AndroidManifest.xml and info.plist file for enabling plugin permissions
Whereas I would like to add the plugins at one place and it should update in appropriate Android and iOS files, similar to that of config.xml file configuration in cordova apps.
Are there any libraries available to implement in this way ?
Thanks
Unfortunately no. Adding libraries that deal with permissions has always been a bit of a struggle in react native, where you have to touch the android and iOS files and often times specify why your app requires those permissions in the first place. It gets a bit more complicated as different android versions have different ways to deal with permissions.
The good news is that most of the libraries you'll want to add provide a detailed documentation on how to set them up properly which does not take too long after you get the gist of it.
On Android native to separate each application feature, structured the project, implementing architecture component and to make it easier to work in a team you can use modularization, so each person can focus on their respective work by focusing only on the module. If I want to make a flutter application with examples of 3 application features (login, register, profile) and want to implement modularization for each feature to make it easier to work as a team. How do you implement the modular? Are there references to its best practices for modularizing Flutter? Because if on Android Native there are already many related articles while I check for Flutter it hasn't found it yet.
Create each feature as a package(library) and add it whenever you want to the main app. For example in my app I use main.dart as a navigator manager and each screen is in different packages.
And this is an example of implementing it: https://github.com/rrifafauzikomara/flutter_modularization
Using flutter to launch other applications on both the platform (Android/iOS). I know we can use url_laucher to launch applications like Gmail or Google map.
Can it also be used for launching my own application?
If "YES", is it possible to get some data back from my other application to flutter application?
If "NO" then is there any other way to do this. My goal is to get the data (like a simple string) back from my other app.
NOTE: Constraint is that I have to use flutter Widgets or packages and not touch the native directories.
Yes, you can use url_launcher to launch your own application provided your application has appropriate url schemes defined.
No, you cannot get back any data by launching an application with url_launcher
Is there a way to achieve this only using flutter widgets and existing plugins?
Yes, only on android. There seems to be a flutter_share plugin that allows you to share data to other apps and receive data shared by other apps.
Hope that helps!
I need to pass data to the website and do something with that and return code as result to my flutter app through the link and continue operation on the app, but I do not know how to do it.
I am beginner in flutter!
please help me!
To Open flutter app from a link, We have to use Platform's url scheme. The procedure is as follows.
Add Url Scheme to Native environment.
Add the plugin for url scheme.
If you would like to get some string or number, you have to decode given url with regular expression.
I recommend you to start from iOS's implementation because it's more simple than Android's. Good Luck!!
