[Download] Customizable Note Taking App Flutter and Kotlin Source Code

THE SOURCE CODE

This is the source code of a real published note taking app on Google Play Store: FunNotes https://play.google.com/store/apps/details?id=dev.farol.funnotes

It’s a fully functional note taking app ready to be rebranded and reskinned.

* For live preview, please install the app(free)
https://play.google.com/store/apps/details?id=dev.farol.funnotes

* For more details about the app, please visit the store
https://play.google.com/store/apps/details?id=dev.farol.funnotes

Currently it’s only available on Android but should be possible to be ported with relative ease to other platforms as
the source code is written in Flutter.

Features

• written in the cross-platform languages Flutter and Kotlin
• already integrated In-App purchases for premium upgrades
• uses best packages for main app features like flutter_quill for the text editor, share_plus for sharing, and
  pigeon for host API abstraction
• uses SQLite for high performance data lookup
• custom database migration system handles database versioning and allows you to add database migrations easily
• lazy note list-items rendering for high performance list, no problem handling huge list of notes, eg. even with
  tens of thousands notes, only a few of them are processed and rendered



The app is built with Flutter and Kotlin. I use VSCode as the editor and assume that you would do the same.

Limitations

The code is specifically designed for Android, without consideration for any other platform.

Getting Started

• obtain and put your google-services.json into the android/app folder. You might want to read Add Firebase
  to your Android project | Firebase for Android (google.com)
• copy android/key.properties.example to android/key.properties and update accordingly
• replace all occurrences of com.example.mynotesapp to your package id
• replace all occurrences of mynotesapp
• rename the folders android/app/src/main/kotlin/com/example/mynotesapp to reflect the new package id
• update the appTitle in the lib/src/globals.dart file
• update the string resource app_name in the android/app/src/main/res/values/strings.xml file
• test build the project, see the Deployment section below

* Note that you should setup Play Store API access for play billing to work, you can confirm the play billing works
when your in-app products are showing on the UpgradeDialog.

Deployment

There is no server deployment, so this is simply building the package to be uploaded to the Google Play Store.

Assuming you have Flutter installed, the deployment is straightforward of running the following scripts in the
project folder:

• ./bump-buildversion

  This will increase the build version in pubspec.yaml (the number after the + sign on the line version:
  1.0.0+1 in the file)

• ./build-appbundle

  This will simply run flutter build appbundle which generates the .aab file which you would need to upload to
  the Google Play Store when creating a release

Design Details

The app consists of a few screens which have widgets subscribed to some states. A state is simply just a group of
reactive variables and some methods for doing app business logic. The states might use some repositories which
handle reading and writing data to the database.

Logical View

Screens

The app consists of just a few screens:

• HomeScreen: this is the main screen that shows the list of notes for the currently selected category. Users can
  select the active category from the list of category tabs. On the top bar there would be some buttons that are
  currently configured to be shown,they are: Search, Add Note, Compact/Full View, Settings, and Menu buttons
• SettingsScreen: shows options to configure which buttons are visible on the top bar and the note item on the
  Home screen. There’s also appearance settings which are only available in the Pro Edition of the app (users will
  need to purchase a paid upgrade). There’s also options to export or import the data and also options to manage
  hidden notes password
• ArchiveScreen: shows the list of archived notes. Here users can choose to select notes to be unarchived or
  deleted. The deleted notes will be shown on the Trash screen
• TrashScreen: shows the list of deleted notes. Here users can choose to select notes to be restored/undeleted or
  permanently deleted
• NoteScreen: shows the note editor. The editor supports rich text editing and embeds (only available to Starter
  Edition). Users can also add annotations/drawings which are shown on top of the text and images/videos embeds

States

States are split according to their domain to minimize widget updates (only widgets that are subscribed to the states
will be rebuilt). The states are:

• CategoryState: handles category business logic, including: adding, deleting, patching, reordering categories
• NoteState: handles note business logic, including: adding, deleting, archiving, restoring, reordering, and
  getting notes for current active filters of archived, deleted, hidden, and search query filters
• DragState: provides notes and categories dragging states
• SettingsState: handles settings business logic
• EditState: handles notes editing business logic
• FocusState
• VendingState: provide current license tier state

Repositories

There are few repositories in the app which handles reading and writing data to the database. They are grouped
according to their domain, which are:

• CategoryRepository
• NoteRepository
• SettingsRepository
• VendingRepository

Database

The app uses SQLite to store all the data which consists of notes, categories, settings, and cached purchases.

Database Migration

Migrating the database is simply done by opening the repositories/migrations.dart file and adding another migrate()
call to the bottom of the list in the migrateAll function.

* Note that the migrate() calls should never be reordered after publishing the app to maintain correct version check
order, otherwise some migrations won’t be executed. This is a tradeoff from using the switch/case structure which
has more boilerplates when adding a migration.
