swift – Flutter to iOS – Use FlutterMethodChannel to iOS recordsdata in Goal C

I’ve a working Flutter Undertaking.

Then I’ve to hook up with a printer. This printer firm offered an API/SDK for me to eat. The code is written in a .h and .a file.

That is simply an iOS connection, no want for Android.

To check a easy connection, these are what I did:

1. I created a folder inside ios/Runner mission and named it “PrinterCheck”, this folder accommodates the .a and .h recordsdata they offered.
2. I modified my AppDelegate

import Flutter

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func software(
    _ software: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    let controller : FlutterViewController = window?.rootViewController as! FlutterViewController;
    let methodChannel = FlutterMethodChannel(title: "PrinterCheck", binaryMessenger: controller.binaryMessenger)
    
    methodChannel.setMethodCallHandler{
      (name: FlutterMethodCall, consequence: FlutterResult) -> Void in
        if("printHello" == name.technique){
          //TODO: execute a easy print to ensure it connects to the recordsdata
          consequence(true);
        } else {
          consequence(FlutterMethodNotImplemented)
        }
    }

    GeneratedPluginRegistrant.register(with: self)
    return tremendous.software(software, didFinishLaunchingWithOptions: launchOptions)
  }
}

3. I created a .m file with a easy printHello technique returning a false bool worth simply to check a connection. I put this .m file in the identical folder the place the .h and .a are situated.

- (BOOL)printHello:(NSString *)printValue {
    return false;
}

4. And in Dart, I invoke the strategy

const platform = const MethodChannel('PrinterCheck');
var consequence = await platform.invokeMethod('printHello', {"printValue": "check"});

I need to understand how I can invoke from the TODO line the printHello from .m file. The consequence(true) is working as is however I need to print false from .m file as a substitute. Thanks.
