Flutter: Unhandled exception: MissingPluginException(No implementation found for method getAll on channel plugins.flutter.io/shared_preferences) : <p>My Flutter application uses the Flutter SharedPreferences plugin and send values to the iOS side with platform.invokeMethod. If I start the application, I have this error:</p>

<pre><code>[VERBOSE-2:dart_error.cc(16)] Unhandled exception:

</code></pre>

<p>If I comment the function to send the value to iOS side, the error is not displayed and the SharedPreferences is working.</p>

<p>Someone can help me?</p>
