What im trying to do is showing a list of assignments and have buttons at the bottom to let the user to select which function they want but when the data becomes a lot and my buttons got push below the screen, i was hoping for the buttons to stay on the screen no matter how many data is generated, buttons will not get push down and the button does not block the visuals of the data, i got an image below to show that example at here
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter/material.dart';
import 'package:fyp/assignment/ViewComplete.dart';
import 'ReassignEmployee.dart';
import 'ViewAssigned.dart';
import 'ViewUnassigned.dart';
class assignmentPage extends StatefulWidget {
const assignmentPage({Key? key}) : super(key: key);
@override
State<assignmentPage> createState() => _assignmentPageState();
}
class _assignmentPageState extends State<assignmentPage> {
TextEditingController searchController = TextEditingController();
String searchText = '';
String id = '';
CollectionReference allNoteCollection =
FirebaseFirestore.instance.collection('Assignment');
List<DocumentSnapshot> documents = [];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('View Assignment'),
),
body: SingleChildScrollView(
padding: const EdgeInsets.all(8.0),
child: Column(
children: [
TextField(
controller: searchController,
onChanged: (value) {
setState(() {
searchText = value;
});
},
decoration: InputDecoration(
hintText: 'Search...',
prefixIcon: Icon(Icons.search),
),
),
StreamBuilder(
stream: allNoteCollection.snapshots(),
builder: (ctx, streamSnapshot) {
if (streamSnapshot.connectionState ==
ConnectionState.waiting) {
return Center(
child: CircularProgressIndicator());
}
documents = streamSnapshot.data!.docs;
if (searchText.length > 0) {
documents = documents.where((element)
{
return
( element.get('carPlate').toString().
toLowerCase().contains(searchText.toLowerCase()) ||

return ListView.separated(

}
I have no idea how to do it, hope someone can guide me, really thanks a lot
You can use Stack and Positioned to pin buttons to the bottom of screen, like this:
class assignmentPage extends StatefulWidget {
const assignmentPage({Key? key}) : super(key: key);
@override
State<assignmentPage> createState() => _assignmentPageState();
}
class _assignmentPageState extends State<assignmentPage> {
TextEditingController searchController = TextEditingController();
String searchText = '';
String id = '';
CollectionReference allNoteCollection =
FirebaseFirestore.instance.collection('Assignment');
List<DocumentSnapshot> documents = [];
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('View Assignment'),
),
body: Stack(
children: [
SingleChildScrollView(
padding: const EdgeInsets.all(8.0),
child: Column(
children: [
TextField(
controller: searchController,
onChanged: (value) {
setState(() {
searchText = value;
});
},
decoration: InputDecoration(
hintText: 'Search...',
prefixIcon: Icon(Icons.search),
),
),
StreamBuilder(
stream: allNoteCollection.snapshots(),
builder: (ctx, streamSnapshot) {
if (streamSnapshot.connectionState ==
ConnectionState.waiting) {
return Center(child: CircularProgressIndicator());
}
documents = streamSnapshot.data!.docs;
if (searchText.length > 0) {
documents = documents.where((element) {
return (element
.get('carPlate')
.toString()
.toLowerCase()
.contains(searchText.toLowerCase()) ||
element
.get('custName')
.toString()
.toLowerCase()
.contains(searchText.toLowerCase()) ||
element
.get('date')
.toString()
.toLowerCase()
.contains(searchText.toLowerCase()) ||
element
.get('employee')
.toString()
.toLowerCase()
.contains(searchText.toLowerCase()) ||
element
.get('id')
.toString()

.contains(searchText.toLowerCase()) ||
element

element

element
