Why do we use a Ticker in Flutter?
Ticker in Flutter is a refresh rate of our animation. It is a class that sends a signal at a regular interval, i.e., around 60 times per second. We can understand it with our watch, which tics at regular intervals. At each tick, Ticker provides a callback method with the duration since the first ticks at each second, after it was started. Even if the tickers started at different times, they always synchronized automatically.
