Consegui aplicar um fundo abaixo do Scaffold
(e até mesmo ele AppBar
) colocando o Scaffold
sob a Stack
e definindo a Container
na primeira "camada" com o conjunto e fit: BoxFit.cover
propriedade da imagem de fundo .
Tanto o Scaffold
quanto AppBar
deve ter o backgroundColor
conjunto como Color.transparent
e o elevation
de AppBar
deve ser 0 (zero).
Voilà! Agora você tem um bom fundo abaixo de todo o Scaffold e AppBar! :)
