如何去除 flutter gridView 间距

Question

I found that when I set my crossAxisCount to 2 n the gridView will have a white divider, as soon as I start scrolling, it will flicker. If my crossAxisCount is 2 n+1, that won't happen, I tested the official demo as well,but I don't want these dividers, so how do I get rid of them?

2n items:

2n+1 items:

This is my code:

gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
            crossAxisCount: 2,
            crossAxisSpacing: 0,
            mainAxisSpacing: 0,
          ),

Answer 1

Its is because as first image, There is 2 items in a row. And In your code

crossAxisCount:2

crossAxisCount is denoted for The number of children in the cross axis.

So, If you want to show lines in grid item set this exact number of items in row. If you dont want this set zero.
