GridView in Flutter - Learn About GridView In Depth


When we need widgets stacked like in a grid, we use GridView. There are two main ways in which you can use a GridView. 

First Method, Using GridView.count()

GridView.count requires 2 things, the first is cross axis count which tells how many boxes or grids will be there in one row.
The second is children property which takes in  a list of widget.


Second Method, Using GridView.builder()

GridView.builder() takes in various parameters, one is itemCount which takes in number of items we want to display. Other required property is gridDelegate controls the layout of the tiles in gridView and the last property which we will talk about is itemBuilder which is similar to the one used in List View. itemBuilder takes in a function with two parameters, context and index. context tells where to place the child on screen or basically which context to place the child in and index is a number which runs through 0 to itemCount - 1.

Text Widget In Depth - Flutter

Text widget is very commonly used as an independent widget or as a sub widget in some other widget. E.g. as a child to a RaisedButton. Here is a small code which uses almost all the properties you might use when developing flutter application for Text Widget and also shows how you can use Text.rich() for multiple formatting of the text. import 'package:flutter/material.dart' ; void main() { runApp(MyApp()); } class MyApp extends StatelessWidget { @ override Widget build(BuildContext context) { return MaterialApp( debugShowCheckedModeBanner: false , home: HomePage(), ); } } class HomePage extends StatefulWidget { @ override _HomePageState createState() => _HomePageState(); } class _HomePageState extends State<HomePage> { @ override Widget build(BuildContext context) { return Scaffold( bo...
