Petit Rappel 3

Nouveaux canaux de distribution Flutter for : Android ● ● iOS Linux ● ● Windows OSx ● Exemple d'une application Flutter sur Linux 4

Alternative viable à Electron ? 5

Bénéfique pour le dev mobile Émulateur : Client Flutter Desktop : ● Démarrage lent ● Démarrage rapide ● Fixé à une résolution ● Runtime Redimensionnable RAM ~1 Go RAM ~100 Mo ● ● App size ~700 Mo App size ~20 Mo ● ● Side Note: Development of Cordova plugins is a real pain. 6

Architecture API Developer Shells for : ● Android ● iOS Low level API Embedder API Engine as a library Engine + Embedder = Shell 7

Let's build an simple Embedder ! 8
