Introduction

Source of inspiration

“One Day list ” is a small, simple and beautiful app， It can help you keep track of your daily plans. If you happen to have the habit of writing a mission plan, then it must be perfect for you.

For users and developers, I will introduce them separately

Before we start, you can take a look at the demo:

Introduction to the user

Colorful Themes

In the app, you can switch between the theme colors in the theme switching interface.The app comes with six default themes, which are the color combinations I've chosen over many attempts. You can also choose a custom theme color.

Colorful Task Icons

In the app, each task comes with an icon, and the app provides all the Material Design style icons that Flutter comes with. You can customize with any color.

Diverse Custom Combinations

In the app, there are a number of other operations that you can customize.

For example, the head of the homepage slide bar displays content, of course, there are some other operations that you will experience on your own.

Done List

When you have completed a task, the task will be moved from the home page to the done list page, where you can see some additional information about the task.

Then, the introduction to the user ends here.

The following is the time for the majority of developers!

Introduction to the Developer

If you have a strong interest in Flutter and have been slow to act, then don't hesitate, hurry up! This project is perfect for getting started with Flutter.

Let me introduce you to the internal structure of this project.

Packages

Some very good packages are used in the project, and I am especially grateful to these developers for keeping my hair healthy.

Below are the information about these packages.

package	explain
dio	network request
shared_preferences	local storage
provider	state management
test	unit test
carousel_slider	slide control
circle_list	circle list
intl	change language
sqflite	sqlite database
flutter_colorpicker	color picker
cached_network_image	image cache
image_picker	image picker
permission_handler	request for permissions
path_provider	get path
image_crop	image crop
flutter_svg	svg pictures
package_info	get package info
flutter_webview_plugin	webview
pull_to_refresh	pull to refresh data
photo_view	show the picture
url_launcher	open app store
open_file	open apk file
flare_flutter	flare animation
encrypt	encrypt password

Project Structure

The state management framework used by the project is Provider , and the architecture of the entire project is as follows

• The View layer is used to display layouts and is a variety of StatelessWidget pages wrapped by ChangeNotifierProvider
• The Model layer is used to process data and is a variety of Model classes that inherit ChangeNotifier
• The Logic layer does not save any data, only logical operations

Does it look like the MVP pattern in Android? In fact, they are all similar, but the names are slightly different. You can also think of the above mode as the MVP mode.

Flutter is particularly well suited for this architectural model, because the view changes with the data, you basically don't have to care about the View, just go and operate on the data.

Directory Structure

The project directory structure is as follows:

├── android
├── build
├── images
├── intl.sh
├── ios
├── lib
├── local_json
├── pubspec.lock
├── pubspec.yaml
├── res
├── svgs
├── test
└── todo_list.iml

Let me explain the other directories besides lib:

directory	explain
images	For storing various pictures
local_json	I encapsulate the Icon information of Flutter into a Json file and store it in this directory
res	Store the language files generated by the "intl" plugin
svgs	Store images in svg format

Then the lib directory

directory	explain
config	Store various configuration classes, such as Dio request encapsulation class, etc.
database	Store database operation related classes
i10n	Class for storing internationalized related operations
items	Item class that stores part of the List list
json	Various network requests, databases, etc. related json files
logic	Locig layer directory
model	Model layer directory
pages	Store each page, which is the directory of the View layer
utils	Packaged tools, such as file operations
widgets	custom widgets

ToDo

• Icon search function
• Feedback display wall
• Email account login
• Custom task details page font size
• Geek news
• Whether to show the opening animation

Note: The current project running environment is the version of flutter 1.7.8 hotfix. The modified version has more destructive fixes than before.
If your version of flutter is lower than the current version, some third-party libraries that are dependent on the project will not run. Please lower their version at that time.

The following is a third-party library that needs to be modified under version 1.5.4.

-   flutter_svg: ^0.12.4+2
-   image_crop: ^0.2.1
-   flare_flutter: ^1.5.4
-   photo_view: ^0.3.3

If you think this app is good, or if this project helps you, give this project a Star. The project will continue to be updated and maintained afterwards.！
