remove excess space at the bottom of my pageview.builder widget - flutter

Question

I am trying to remove the excess space at the bottom of my widget but have not been able to do so. since I am using a page builder with a lot of text. I have tried adding the height manually but its not enough since i cant predict the size of the text.

final String text4 = lorem(paragraphs: 8, words: 2000);
final String text5 = lorem(paragraphs: 12, words: 500);

Ignore this line it is just an excess line. I am trying to remove the excess space at the bottom of my widget but have not been able to do so. since I am using a page builder with a lot of text. I have tried adding the height manually but its not enough since i cant predict the size of the text.

You can try mainAxisSize: MainAxisSize.min in your columns and remove height: double.maxFinite:
class FeedsDetailPage extends StatelessWidget {
const FeedsDetailPage({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return const FeedsDetailView();
}
}
class FeedsDetailView extends StatelessWidget {
const FeedsDetailView({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
final String text1 = lorem(paragraphs: 2, words: 55);
final String text2 = lorem(paragraphs: 9, words: 500);
final String text3 = lorem(paragraphs: 10, words: 400);
final String text4 = lorem(paragraphs: 8, words: 2000);
final String text5 = lorem(paragraphs: 12, words: 500);
final textList = [
text3,
text4,
text5,
];
