+## [0.6.0-nullsafety]
+Now with null safety :) - Thanks Ali1Ammar!
+
+## [0.5.5]
+Add optional `createParticlePath` function to pass in a custom `Path` for the conveti (for example a Star path, instead of the default Rectangle path). Example updated. Thanks Artur-Wisniewski.
+Fix: Animation stop event not firing. Thanks WieFel.
+
 ## [0.5.4+1]
 Fix: Call play on the confetti controller from `initState`.

 ## Getting Started  
 
 To use this plugin, add `confetti` as a [dependency in your pubspec.yaml file](https://flutter.io/platform-plugins/). 
 
-See the example to get started quickly.
+See the example to get started quickly. To generate the platform folders run:
+
+```dart
+flutter create .
+```
+
+in the example folder.
 
 To begin you need to instantiate a `ConfettiController` variable and pass in a `Duration` argument. The `ConfettiController` can be instantiated in the `initState` method and disposed in the `dispose` method.
 
@@ -31,6 +42,36 @@ Other attributes that can be set are:
 * `gravity` -> change the speed at which the confetti falls. A value between 0 and 1. The higher the value the faster it will fall. Default is set to `0.1`
 * `particleDrag` -> configure the drag force to apply to the confetti. A value between 0 and 1. A value of 1 will be no drag at all, while 0.1, for example, will be a lot of drag. Default is set to `0.05`
 * `canvas` -> set the size of the area where the confetti will be shown, by default this is set to full screen size.
+* `createParticlePath` -> An optional function that retuns a custom `Path` to generate unique particles. Default returns a rectangular path.
+
+
+### Example of a custom `createParticlePath`
+
+```dart
+Path drawStar(Size size) {
+    // Method to convert degree to radians
+    double degToRad(double deg) => deg * (pi / 180.0);
+
+    const numberOfPoints = 5;
