cellBuilder property

void Function(int row, int column)? cellBuilder
getter/setter pair

Builds the widget cells for a window of rows, [first, last).

Set by the section's element. It runs inside performLayout, through invokeLayoutCallback, because only layout knows which rows are on screen: the grid scrolls by relaying this object out, not by rebuilding, so a list of children decided in build would always be a frame behind.

Implementation

void Function(int first, int last)? cellBuilder;
