No way to position the splash at the bottom of the screen.

You can't really position the splash widget at the bottom of the screen.

You can try doing something like this:

AnimatedSplashScreen(
      duration: 3000,
      centered: true,
      splash: Container(
        child: Column(mainAxisAlignment: MainAxisAlignment.end, children: [
          const Text(
            "Title",
            style: TextStyle(
              fontSize: 64,
              fontWeight: FontWeight.bold,
            ),
          ),
          Image.asset('assets/images/splash.png')
        ]),
      ),
      splashIconSize: double.infinity,
      nextScreen: const LoginWidget(),
      splashTransition: SplashTransition.fadeTransition,
      pageTransitionType: PageTransitionType.fade,
    );
