Tab View Content

Tab View Content is the widget that shows the actual content for the currently selected tab. It works together with:

• Tab Controller → manages which tab is selected

• Tab Bar → lets the user switch tabs

Whenever the selected tab changes, Tab View Content updates to display the corresponding screen/content.

Use Cases

You use Tab View Content when:

• You have multiple sections of content under different tabs, such as:

  • Product page → Overview, Details, Reviews

  • Profile → Posts, About, Activity

  • Dashboard → Summary, Analytics, Logs

• You want users to switch between content without leaving the screen.

• You want each tab to have:

  • Its own scrollable content

  • Its own UI/state

  • Smooth transitions between sections

It’s ideal for building multi-tab experiences where each tab has a distinct layout or data.

Core Concepts

• Content Area for Tabs

  • Tab View Content is essentially the page area below the Tab Bar.

  • It listens to the Tab Controller’s selected index and shows the relevant tab’s content.

• Scroll Behavior

  • With isScrollable, you can decide if each tab’s content is scrollable vertically (e.g., long lists, forms, feeds).

• State Preservation

  • keepTabsAlive ensures each tab’s state (scroll position, form inputs, etc.) is preserved when you switch tabs.

  • Without it, content might rebuild/reset when you navigate away from a tab.

• Viewport Fraction

  • viewportFraction controls how much of the screen each tab’s page occupies.

  • Mostly useful for paged / swipe-like layouts, where you might show a portion of the next/previous tab for visual hints.

Properties

Property	Description
isScrollable	If true, the content within each tab can scroll (e.g., for long lists or detailed pages). If false, content stays fixed within the available space.
keepTabsAlive	If true, the state of each tab's content is preserved when it goes off-screen. This helps keep scroll position, user input, and loaded data intact when switching between tabs.
viewportFraction	Defines what fraction of the viewport each tab's content should use. A value of 1.0 typically means each tab fills the full width; values less than 1.0 can show a peek of adjacent tab content.
