Fix IONIC Error: Unknown argument: platform

npm install @ionic/cordova-builders

Copy this to angular.json

"ionic-cordova-build": {
  "builder": "@ionic/cordova-builders:cordova-build",
  "options": {
    "browserTarget": "app:build"
  },
  "configurations": {
    "production": {
      "browserTarget": "app:build:production"
    }
  }
},
"ionic-cordova-serve": {
  "builder": "@ionic/cordova-builders:cordova-serve",
  "options": {
    "cordovaBuildTarget": "app:ionic-cordova-build",
    "devServerTarget": "app:serve"
  },
  "configurations": {
    "production": {
      "cordovaBuildTarget": "app:ionic-cordova-build:production",
      "devServerTarget": "app:serve:production"
    }
  }
}

Then you can run

ionic cordova run android --target=emulator-5554
