Flutter Horizontal Page Slider animation signin/sign up form

Direction-aware slide-in/slide-out animations. build a likee- style horizontal page switching system for my flutter app. and do nice animation on signin-signup form.

requirements:
1. Implement a direction-aware page animation:
• When switching to the right, the new page slides in from the right.
• When switching to the left, the new page slides in from the left.
• Slide-in and slide-out must both work without breaking each other.

2.Use:
• PageController or AnimatedSwitcher
• Custom slideIn / slideOut transitions based on direction
• Fast, smooth animations similar to Likee/TikTok.

3.Add a top tab bar with 3 tabs:
• HOME
• ALBUM
• SEARCH
The underline/indicator should animate smoothly when switching tabs.

4.No lag when switching pages — transitions must be 60fps smooth.
5.Clean, modular code:
• Keep page logic separate.
• Keep animation logic separate.
