+# Teddy
+
+<img align="right" src="https://i.imgur.com/hJU9Obt.gif" height="250">
+
+An example built using [JCToon's](https://www.2dimensions.com/a/JuanCarlos/files/flare/teddy/preview) Flare File as a custom UI component. <br/>
+Teddy will follow the cursor as you type or move it around.
+
+## Overview
+
+The basic idea is to use the `ctrl_face` node in JCToon's file to change the direction of Teddy's gaze, as it's shown here in the gif to the right.
+
+This is done by using [custom `FlareControls`](lib/teddy_controller.dart), available in `/lib/teddy_controller.dart`.
+
+`FlareControls` is a custom implementation of the `FlareController` interface. <br/>The interface and can be found in [flare_actor.dart](../../lib/flare_actor.dart#L13-L17) and it has three methods:
+
+```
+abstract class FlareController {
+  void initialize(FlutterActorArtboard artboard);
+  void setViewTransform(Mat2D viewTransform);
+  bool advance(FlutterActorArtboard artboard, double elapsed);
+}
+```
+
+<img align="right" src="https://i.imgur.com/WdjurVo.gif" width="300" />
+
+An instance of `TeddyController` is passed to the `FlareActor` in [`/lib/main.dart`](lib/main.dart#L77). This ties the controller to this widget, and allows it to use the three overrides to perform custom actions:
+
+```
+FlareActor(
+    "assets/Teddy.flr",
+    controller: _teddyController,
+    [...]
+)
+```
+
+In this example, `initialize()` will grab the reference to the `ctrl_face` node through the library call `artboard.getNode("ctrl_face")`. 
+
+Moreover, by [extending `FlareControls`](../../lib/flare_actor.dart#L462), `TeddyController` can take advantage of a concrete implementation of this interface:
+- `play(String animationName)`
+- `advance(double elapsed)` - a base implementation which advances and mixes multiple animations
