StaggeredGridView is undefined
1,719
Solution 1
Use Version:
dependencies:
flutter_staggered_grid_view: ^0.4.0
Solution 2
The pub.dev documentation for the plugin doesn't suggest anything about the method being deprecated or scrapped in the latest version i.e flutter_staggered_grid_view 0.6.1
. I tried using flutter_staggered_grid_view: ^0.4.0 but that didn't work either. The workaround seems to be to use version 0.3.1
which then recognized the StaggeredGridView
method.
