lib/main.dart:

import 'package:allaboutflutterblog/tuts/customFonts.dart';
import 'package:flutter/material.dart';

void main() {
  runApp(
    MaterialApp(
      home: CustomFonts(),
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        fontFamily: "Montserrat",
        brightness: Brightness.dark,
      ),
    ),
  );
}

import 'package:flutter/material.dart';
import 'package:font_awesome_flutter/font_awesome_flutter.dart';
import 'package:random_color/random_color.dart';

class CustomFonts extends StatefulWidget {
  @override
  _CustomFontsState createState() => _CustomFontsState();
}

class _CustomFontsState extends State<CustomFonts> {
  final List _items = List.generate(100, (i) => i + 1);
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        // FontAwesomeIcon
        leading: Icon(FontAwesomeIcons.alignLeft),
        title: Text(
          "Custom Fonts and Themes",
          style: TextStyle(fontSize: 15.0),
        ),
        centerTitle: true,
        backgroundColor: Colors.deepPurple,
        actions: <Widget>[
          // FontAwesomeIcon
          Icon(FontAwesomeIcons.search),
        ],
      ),
      body: OrientationBuilder(
        builder: (BuildContext context, orientation) {
          return GridView.builder(
            itemCount: _items.length,
            itemBuilder: (BuildContext context, orientation) {
              return Container(
                alignment: Alignment.center,
                color: RandomColor().randomColor(),
                child: Text(
                  "Grid ${orientation + 1}",
                  style: TextStyle(color: Colors.white, fontSize: 22.0),
                ),
              );
            },
            gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
              crossAxisCount: orientation == Orientation.portrait ? 2 : 4,
            ),
          );
        },
      ),
    );
  }
}

pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.2
  http: ^0.12.0+2
  random_color: ^1.0.3
  font_awesome_flutter: ^8.4.0

dev_dependencies:
  flutter_test:
    sdk: flutter

  fonts:
    - family: Montserrat
      fonts:
        - asset: fonts/montserrat/Montserrat-Regular.ttf       
          style: italic

Explanation:

  • Add font_awesome_flutter 8.4.0 in your pubspec.yaml file Also add custom font.
  • Wrap the widget with OrientationBuilder in order to change the view of the screen when the orientation is changed.
  • Wrap the root widget with Theme or we can use Themes in the MaterialApp widget.

Flutter Development (Day-16): All source code :  Click Here . Sorry for the last two days I haven't posted anything because I am ready to leave my hometown to attend my college.Is there anyone from AndhraPradesh or Tamilnadu .If yes please provide your city name in the comment section. In this post we are going to proceed the next level of our todo app.We are going add animations to our app,Code clean Up and some UI changes. We add the animation to our FloationgActionButton.You may ask why you haven't add animations to others as well? I tried it but it is looking weird. Adding animations to  FloationgActionButton is very much similar to our previous basic animation tutorial. From the next we are going to deal with some of the important widgets which we will be using in further tutorials.

Flutter Development (Day-11): In the last post we have discussed about how to implement brand new Todo application. All source code :  Click Here . Building its User Interface. How to display the data. How to remove the items from the List by tapping the Delete Icon or by Swiping it. Showing which item is deleted in the form of SnackBar. And finally modify some UI stuff. If you want to copy the exact same code  click here . List _todos = []; First of all create a empty list which will be holding all of our Todo's. When we tap on the ADD button we have to perfom some operation see below.   _validateForm() {if (_key.currentState.validate()) {setState(() {_todos.add(_controller.text);});_controller.clear();Navigator.of(context).pop();}} Here we have used setState () in order to refresh every single time of changing the data in the TextField and then we add the text to _todos list. Then we clear the data in the TextField and go back to homeScreen .
