I have the same problem for Android, I could not fixed it

There is an example here on how to add the proguard.cfg
Stackoverflow proguard

You need to change the build.gradle file also not just adding the file into android/app. Android has default names for proguard and you have to set the name the new name of the file.

For example
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard.cfg'

Is the above correct?

Even though the problem persists, Investigating the exception found this Flutter Issues Proguard

Hope it helps

[kevinbayes]

@tetteu777 can you please provide a sample application that reproduces this error? I can then ave a look into it.

[gabrielrbarbosa]

Same issue here, using this example project. Tried to add proguard file but it gives the same error.

[rlechetaudemy]

Same error here:
Doctor summary (to see all details, run flutter doctor -v):

Hello guys

I managed to make it work but on another project.

As the exception says Trying to create a platform view of unregistered type: flutter_zoom_plugin
there is a problem registering the flutter_zoom_plugin.

The registering occurs at android/app/src/main/java/io/flutter/plugins/GeneratedPluginRegistrant.java

This is the code of the class at the example

package io.flutter.plugins;

import androidx.annotation.Keep;
import androidx.annotation.NonNull;

import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.embedding.engine.plugins.shim.ShimPluginRegistry;

/**
 * Generated file. Do not edit.
 * This file is generated by the Flutter tool based on the
 * plugins that support the Android platform.
 */
@Keep
public final class GeneratedPluginRegistrant {
  public static void registerWith(@NonNull FlutterEngine flutterEngine) {
    ShimPluginRegistry shimPluginRegistry = new ShimPluginRegistry(flutterEngine);
      com.decodedhealth.flutter_zoom_plugin.FlutterZoomPlugin.registerWith(shimPluginRegistry.registrarFor("com.decodedhealth.flutter_zoom_plugin.FlutterZoomPlugin"));
  }
}

The class is generated by Flutter so, there is no point fixing anything here. But I have another flutter project where the Generated class is

package io.flutter.plugins;

import io.flutter.plugin.common.PluginRegistry;
import io.flutter.plugins.deviceinfo.DeviceInfoPlugin;
import com.decodedhealth.flutter_zoom_plugin.FlutterZoomPlugin;

/**
 * Generated file. Do not edit.
 */
public final class GeneratedPluginRegistrant {
  public static void registerWith(PluginRegistry registry) {
    if (alreadyRegisteredWith(registry)) {
      return;
    }
    DeviceInfoPlugin.registerWith(registry.registrarFor("io.flutter.plugins.deviceinfo.DeviceInfoPlugin"));
FlutterZoomPlugin.registerWith(registry.registrarFor("com.decodedhealth.flutter_zoom_plugin.FlutterZoomPlugin"));
  }

  private static boolean alreadyRegisteredWith(PluginRegistry registry) {
    final String key = GeneratedPluginRegistrant.class.getCanonicalName();
    if (registry.hasPlugin(key)) {
      return true;
    }
    registry.registrarFor(key);
    return false;
  }
}

One of the things that is wierd is the
import com.decodedhealth.flutter_zoom_plugin.FlutterZoomPlugin; missing on the example, but it is a generated file so.... it should work.

The exact same meeting_screen.dart on the example and adding

 flutter_zoom_plugin:
      git:
        url: git://github.com/decodedhealth/flutter_zoom_plugin.git
        ref: 0.0.7

on the other project works.

[rlechetaudemy]

I didn't understand how you solve it, since it is a generated file. I tried to change de code, but it got generated again.

[gfiury]

Solved it with a new flutter project, the GeneratedPluginRegistrant is different and the meeting_screen.dart works. I gotta say that the original problem was for Android, the iOS example always worked for me.

[rlechetaudemy]

What version of flutter are you using? I have this version:
Flutter (Channel master, 1.18.0-11.1.pre

[gfiury]

I have 1.17.2 (Stable for Windows)

[rlechetaudemy]

Can't get it to work :-(
I think the plugin should be update to work like this:
https://flutter.dev/docs/development/packages-and-plugins/plugin-api-migration

[Maadhav]

Any update on this?

[kevinbayes]

@Maadhav if you have a sample small application that can simulate the problem it would be good to post for us to test.

[Maadhav]

I just downloaded the example and ran the program with my app key and secret. But when I join a meeting the error mentioned above just comes, and nothing appears.
Unhandled Exception: PlatformException(error, java.lang.IllegalStateException: Trying to create a platform view of unregistered type: flutter_zoom_plugin

[longvhv]

I have the same error: Unhandled Exception: PlatformException(error, java.lang.IllegalStateException: Trying to create a platform view of unregistered type: flutter_zoom_plugin

[Maadhav]

@longvhv So to use this plugin u will have yo manually create a new project change the amdroid and ios files as told in the Reame. The same error occurred with me when trying to run the example app

[longvhv]

Thank @Maadhav , I will give it a try.

[Bharavi26]

i am getting same error when i run example code...
anyone can please help me or there is any demo code in which flutter_zoom_plugin is integrated ?

[Maadhav]

@Bharavi26 I have uploaded my example on my Github.
https://github.com/Maadhav/zoom_flutter_example
Don't forget to add the necessary keys and secrets in the lib folder.
Hope it helps

[Bharavi26]

Thank you so much @Maadhav sir, I will check that ..I am working on that error from last 2 days,

[romeshn]

I am not able to get it working, below are the steps I followed.

https://github.com/Maadhav/zoom_flutter_example
update appKey, appSecret and userId
flutter pub run flutter_zoom_plugin:unzip_zoom_sdk dev
flutter run
Join meeting
Then I am getting a blank screen.

@romeshn Didn't try with ios yet. Could u pls test if the same issue occurs in android?

Android is working fine for me but when it comes to iOS, I'm getting this error.

Can you please let me know how you got it working on iOS?
