Rendering Flutter kalebu telung wit — Widget tree (konfigurasi), Element tree (widget sing wis diinstal lan dikelola), lan RenderObject tree (layout lan painting). Ngerti pipeline iki nggawe cara Flutter ngobah widget dadi piksel dadi jelas.
Telung wit
WIDGET tree → immutable CONFIGURATION (what you write: the description of the UI)
→ cheap to create/recreate; rebuilt often (build() returns new widgets)
ELEMENT tree → the INSTANTIATED widgets; manages lifecycle and LINKS widgets to render
objects; PERSISTS across rebuilds (this is the key to efficiency)
RENDEROBJECT tree → does the actual LAYOUT, PAINTING, and hit-testing (the heavy objects)
→ expensive; REUSED and updated (not recreated) across rebuilds
