I am creating a lock screen application on flutter for ios and android, I want the application to work in the background, i.e. when the phone screen is turned on, the window for entering the pin code of my application "pops out", how can this be done?
Well, there is no direct solution on flutter yet. For sure there is no solution for ios. You will have to write both java/kotlin and swift/objective c and use the invoke methods to call your native functions.
native is a word we use for the specific platform code. for example native android means java or kotlin and swift or objective c for ios.

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'm new to Flutter, and I noticed that the launch screen for Android take more time than usual for a native app, I followed the instructions here
But for IOS, everything is working fine.
Is there a way to make the launch time for Android faster?
Thanks!
Flutter is a Cross Platform. When ever you to compare with Native then it always slower than Native Apps. Both Android and IOS handling and Behaviour are different so that why you got different for Lunching time..
i am currently facing the following problem and I hope someone can help me out:
I want to write an app in Flutter (yes I already compared this framework to others like React Native and Ionic) but i need to include the motiontag SDK and here is where the problem starts.
The Motion Tag SDK is only available for native App descreptive native programming language (Java/Kotlin, Swift).
Is there a way to include the SDK anyway to flutter??
Like some workaround!
Thanks for helping me out!
Flutter does have communication with native via Platform Channels, so if the sdk is just function calls you could call the function from flutter/dart , and then let the platform channel handle the call to the native function with arguments. If the sdk it's about rendering UI inside flutter then it's more complicated but it's possible as long as you use the boundaries of PlatformView . All the native plugins developed for flutter use this two methods to handle native code/UI
I wanted to know is it possible to check using ionic if iOS device has NFC functionality. I can use "PhoneGap NFC Plugin" but it only has nfc.beginSession() function which isn't what I need because it opens NFC reading window for iOS but I just want to check if available without opening any windows. I know that you can call in swift NFCNDEFReaderSession.readingAvailable() but is there a plugin which offers what I need?
The enabled() method of the phonegap-nfc plugin seems to do exactly what you want on iOS: it internally calls NFCNDEFReaderSession.readingAvailable().
I have a PhoneGap app that I'm testing on webOS, Android, and iPhone. I'm using physical devices as well as emulators (the ones that come with their respective SDKs, not the PhoneGap emulator).
Part of the code uses the navigator.notification.vibrate() and navigator.notification.beep() functions.
All the physical devices I'm using either perform the behavior or ignore it if they're not capable (e.g., the iPod can't vibrate). However, the emulators behave differently.
The Android emulator kills the app whenever the beep() function is called. The iPhone emulator causes the app to hang whenever the vibrate() function is called.
Is there any way to get the emulators to ignore those function calls when they are unable to execute them? That is, is there a way to get them to degrade gracefully so I can test the app both places without having to modify the code specifically for the emulators?
I don't think this is an issue with the emulators. I can use both vibration and audio alerts in my native applications. These both function fine in the emulator. I think it the problem is how PhoneGap is handling these functions in native code. Are you suggesting that these functions work on the device but not the emulator?
