Platform exception error

[prabhunath111]

When I am debugging.
getting null typedResult.

@optionalTypeArgs
Future invokeMethod(String method, [ dynamic arguments ]) async {
print('inside invoke method $method');
assert(method != null);
final ByteData result = await binaryMessenger.send(
name,
codec.encodeMethodCall(MethodCall(method, arguments)),
);
print('result $result');
if (result == null) {
print('result is null');
throw MissingPluginException('No implementation found for method $method on channel $name');
}
final T typedResult = codec.decodeEnvelope(result);

print('typedResult $typedResult');

return typedResult;

}
