未找到在通道插件上写入方法的实现。it_nomads.com/flutter_secure_storage

Question

I was trying to store the login credentials of a user upon login, but I'm getting this error again and again. Things I've tried:

1. Restarting app
2. Uninstalling and reinstalling app
3. updating the flutter_secure_storage to the latest version

Here's the flutter doctor summary

Answer 1

"MissingPluginException" or "Implementation not found" errors thrown by plugins usually occurs when the plugin wasn't properly "installed" in the Flutter project.

These solutions may not be able to inject plugin dependencies into the platform-specific parts of the app. What you can do here is run flutter clean and flutter pub gets to rebuild the dependencies used in the project.

Also check that if that package supports your platform or not.if platform is not supported than find another package with your platform support.

Answer 2

I have stopped the debug the app and restarted the full application, It works for me

Answer 3

When you add a new plugin, you need to re-build the application, the hot re-start doesn't build the application and your newly added is not included in your project unless built again. for that you should run

flutter clean

flutter pub get

flutter run

if still not solved add read this

Answer 4

Generally this problem occurs when 2 or more plugins are incompatible with each other or with the current sdk version To fix this change you kt code to this

package com.pharmdel_business

import io.flutter.embedding.android.FlutterFragmentActivity

class MainActivity: FlutterFragmentActivity() { }

******but if any of you other plugin that only support FlutterActivity will stop working If you face that issue then go to that plugin file and replace FlutterActivity with FlutterFragmentActivity
