// Click stream game

// The reason why streams are used is because most Dart/Flutter libs use streams.
// We can compose streams (processing pipeline) out of easily resuable functions.
// Can be really easy to read streams and understand how they modify data.
// Streams are all about time series data - far easier to do some time-related stuff with streams.
