    SliverChildDelegate should know which children are live (#9073) · 0e43e581
    Adam Barth authored
    This patch adds a notification to SliverChildDelegate that says which
    children are alive after each layout. The delegate can use this
    information to optimize it's underlying model of the children (e.g., by
    discarding models for children that are far outside the live range).
    
    Fixes #9045
