title: Sending Data to Plugins
sidebar_label: Send Data
---
It is often useful to get an instance of a Flipper plugin to send data to it. Flipper makes this simple with built-in support.
Plugins should be treated as singleton instances as there can only be one `FlipperClient` and each `FlipperClient` can only have one instance of a certain plugin. The Flipper API makes this simple by offering a way to get the current client and query it for plugins.
Plugins are identified by the string that their identifier method returns, in this example, "MyFlipperPlugin":
### Android
```java
final FlipperClient client = AndroidFlipperClient.getInstance(context);
// Client may be null if AndroidFlipperClient.createInstance() was never called
// which is the case in production builds.
if (client != null) {
final MyFlipperPlugin plugin = client.getPlugin("MyFlipperPlugin");
plugin.sendData(myData);
}
```
### iOS
```objective-c
FlipperClient *client = [FlipperClient sharedClient];
MyFlipperPlugin *myPlugin = [client pluginWithIdentifier:@"MyFlipperPlugin"];
[myPlugin sendData:myData];
```
### C++
```c++
auto &client = FlipperClient::instance();
// "MyFlipperPlugin is the return value of MyFlipperPlugin::identifier()
auto aPlugin = client.getPlugin("MyFlipperPlugin");
// aPlugin is a std::shared_ptr<FlipperPlugin>. Downcast to expected type.
auto myPlugin = std::static_pointer_cast<MyFlipperPlugin>(aPlugin);
// Alternatively, use the templated version
myPlugin = client.getPlugin<MyFlipperPlugin>("MyFlipperPlugin");
myPlugin->sendData(myData);
```
Here, `sendData` is an example of a method that might be implemented by the Flipper plugin.
