海外TECH	DEV Community	Run java code in Flutter - MethodChannel template	https://dev.to/ramgendeploy/run-java-code-in-flutter-methodchannel-template-15o0	Run java code in Flutter MethodChannel templateThese are notes on running native code on flutter and a quick templates to get started sources at the end Running native code with flutter is accomplished by sending messages using a defined platform channel Using the MethodChannel the flutter app sends and receives messages from the host platform iOS Android Method calls are encoded into binary before being sent and binary results received are decoded into Dart values The data sended through the channel is converted like in the following table Messages and responses are passed asynchronously but the channels method needs to be invoked in the main thread Because of this the main thread can jank if the method takes too long to compute this might be mitigated by sending messages in different threads in the backend more on that in a moment Other characteristic of this is that the Method Channels can t be use in isolates because the main isolate is the only one running in the main thread How to create a methodchannelDefine the methodchannel in the state of the app The name needs to match You can use this as a template for whatever you want to do import dart async import package flutter material dart import package flutter services dart class MyHomePageState extends State lt MyHomePage gt static const platform const MethodChannel com dev app channel name Platform specific code creating the backend in the MainActivity kt or java create the method channel import androidx annotation NonNullimport io flutter embedding android FlutterActivityimport io flutter embedding engine FlutterEngineimport io flutter plugin common MethodChannelclass MainActivity FlutterActivity private val CHANNEL com dev app channel name private fun doSomethingFunction Int return return batteryLevel override fun configureFlutterEngine NonNull flutterEngine FlutterEngine super configureFlutterEngine flutterEngine MethodChannel flutterEngine dartExecutor binaryMessenger CHANNEL setMethodCallHandler call result gt Note this method is invoked on the main thread if call method doSomething val funValue doSomethingFunction if funValue result success funValue else result error UNAVAILABLE Error message null else result notImplemented Call method channel in the flutter app function in the state String valueReceivied default value Future lt void gt getBatteryLevel async String tempValue try final int result await platform invokeMethod doSomething batteryLevel New data result on PlatformException catch e batteryLevel Failed to get new data e message setState valueReceivied tempValue Then execute the function as you see fit You can also use invokeListMethod and invokeMapMethod that are an implementation of invokeMethod however they expect to receive a List or Map More info This way of communicating and executing code with the backend of the platform is not typesafe as it requires the definition of the same datatype in the backend as in the flutter app Another way of doing this is using code generation with Pigeon More info in the pub dev page I will try to make a post about this if i find it interesting You can make Packages to separate the platform specific code for the UI and also publish the package to the Flutter ecosystem Developing Publishing ThreadingThe main thread and where the method channels are executed is also the UI thread so if some computation takes too long to finish the UI might suffer from this So one thing to keep in mind is When your app performs intensive work in response to user interaction this single thread model can yield poor performance unless you implement your application properly Specifically if everything is happening in the UI thread performing long operations such as network access or database queries will block the whole UI When the thread is blocked no events can be dispatched including drawing events From the user s perspective the application appears to hang Even worse if the UI thread is blocked for more than a few seconds about seconds currently the user is presented with the infamous application not responding ANR dialog The user might then decide to quit your application and uninstall it if they are unhappy You can jump from a background thread to the UI thread by doing thison Kotlin Handler Looper getMainLooper post Call the desired channel message here on Java new Handler Looper getMainLooper post new Runnable Override public void run Call the desired channel message here Not sure what the docs meant by this but this might be a way of running the native code in a different thread although I ve tested something similar and I ve experienced erros so more testing needs to be done here if you have any info let me know This is awesome to execute native code or libraries that don t have support in dart in my example this is awesome for ML libraries and get models to run on the device One thing that I ve experience is that when running ML models the UI threads struggles so I will make test on running these models on different threads or making plugins as they run in different threads I did a quick introduction on how to use Pytorch mobile on flutter I m planning on doing a more comprehensive one I going to talk about the use of threads for making things faster and without lag if i find that they work properly Sources Platform channelsDocs MethodChannel	2022-01-29 01:46:21
