Flutter Media Sizing Guide

This guide explains how to control ad media sizing in Flutter Ads SDK using flexible height constraints. Optimize layouts for better responsiveness, performance, and user experience across mobile, web, and desktop apps.

Proper media sizing improves ad visibility, layout stability, and overall monetization performance in Flutter applications.

How Media Sizing Works in Flutter Ads SDK

Media sizing determines how ad content adapts within your layout. By using different height constraints, you can control how ads scale, ensuring consistent UI behavior across different screen sizes and layouts.

Expanded Height

Expands to fill available vertical space inside parent constraints. Ideal for feeds and flexible layouts.

ExpandedHeightConstraint()

Fixed Height

Locks media to a fixed height. Useful when you need strict layout consistency across items.

FixedHeightConstraint(400)

Max Height

Allows media to scale naturally but caps the maximum height. Best for responsive layouts with limits.

MaxHeightConstraint(400)
Choose constraints based on your layout: use Expanded for flexibility, Fixed for consistency, and MaxHeight for balanced responsiveness.
