this is the exception shown on console -:
════════ Exception caught by widgets library ═══════════════════════════════════════════════════════
The following assertion was thrown building LoginPage(dirty, dependencies: [MediaQuery], state: LoginPageState#6cbef(ticker active)):
LoginPageState is a SingleTickerProviderStateMixin but multiple tickers were created.
A SingleTickerProviderStateMixin can only be used as a TickerProvider once.
If a State is used for multiple AnimationController objects, or if it is passed to other objects and those objects might use it more than one time in
