anchored_overlay_engine 1.0.0

Anchored overlay lifecycle engine (positioning, policies, insertion).

anchored_overlay_engine

Anchored overlay engine for Flutter: lifecycle, policies, and positioning without Material/Cupertino dependencies.

This package is an engine/runtime, not a UI component library.

Positioning on pub.dev (short)

anchored_overlay_engine is an engine, not “yet another dropdown/tooltip”. It solves system-level overlay concerns:

• predictable lifecycle (opening/open/closing/closed) and close contract,
• deterministic policies (dismiss/focus/reposition),
• anchored positioning (flip/shift/maxHeight + safe area + keyboard),
• insertion via Flutter primitives (OverlayPortal).

If you are looking for ready-made UI widgets, this is not it. If you need a reliable overlay runtime for your own design system, it is.

Requirements

• Flutter >= 3.10 (OverlayPortal).
