explorer-app's Issues

Publish the Project

migrate android splash screen

W/FlutterActivityAndFragmentDelegate(27310): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.

Upgrade flutter embedding

Do the Full-Flutter app migration

https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

Create READMES

• README for the general project
• README for the Backend
• README for the App

add github actions to lint all the subprojects & execute the tests

Create a Release for GitHub

Deploy the backend on a Server

• Create a deploy key 🔑
• Setup a Webhook on GitHub ↪️
• Setup a WebHook config on the remote server 🌐
• Setup the updatescript for the backend
• Persist the backend running upon reboot

get the correct logos

Add a nice Startup Screen

Function to fetch the Stations from the Server

At the beginning all Apps should fetch the stations from the server (without authentication / identification )

setup the deployment on my server using ansible

currently the deployment on my server https://christian.heusel.eu is set up manually, this should be changed to further test the ansible role.

Flutter Android v2 embedding

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Warning
──────────────────────────────────────────────────────────────────────────────
Your Flutter application is created using an older version of the Android
embedding. It is being deprecated in favor of Android embedding v2. Follow the
steps at

https://flutter.dev/go/android-project-migration

to migrate your project. You may also pass the --ignore-deprecation flag to
ignore this check and continue with the deprecated v1 embedding. However,
the v1 Android embedding will be removed in future versions of Flutter.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The detected reason was:

  /home/chris/Documents/shared_projects/explorer-app/fluttr_app/explorer_app/android/app/src/main/AndroidManifest.xml uses
  `android:name="io.flutter.app.FlutterApplication"`
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Build failed due to use of deprecated Android v1 embedding.

Create a Datamodel for the API

Connect the App to the GraphQL Backend

GraphQL Query not working in release mode

If one builds an APK using flutter and installs it:

flutter apk build

Our first simple query does not work anymore, this could be due to missing assets or something else but has to be investigated.

set up the teams / stations using ansible

for our distributed backend we need to deliver the stations.csv / teams.csv via ansible

Document the different station types and implement sanity checking for answers

Currently we just dump the input of the mutation into the db but some sanity checking is needed so errors in the frontend are detected!

explorer-app/server/graph/mutations.resolvers.go

Lines 26 to 50 in 65ad1ce

	func (r *mutationResolver) CreateAnswer(ctx context.Context, stationNumber int, answerTime time.Time, resultOption *int, resultText *string, resultNumber *float64) (*model.Answer, error) {
	station := &model.Station{}
	findStation := r.DB.First(station, stationNumber)
	if findStation.Error != nil {
	log.Print("Error while finding a matching station for answer: ", findStation.Error)
	return nil, findStation.Error
	}
	answer := model.Answer{
	Station: station,
	AnswerTime: answerTime,
	SynchronizationTime: time.Now(),
	ResultOption: resultOption,
	ResultText: resultText,
	ResultNumber: resultNumber,
	}
	result := r.DB.Create(&answer)
	if result.Error != nil {
	return nil, result.Error
	}
	return &answer, nil
	}

Add Input Page for Answers with number type

Similar to the Text input we need a page for number input. It should be possible to Type numbers and ',' or '.'

Remove the internal dataclasses in the app

Unclear whether we really need this, maybe this can be removed later and replaced by using the generated code.

create a demo mutation in the app

add a data protection website

Add "real" authentication to the backend

We should add some kind of "real" authentication so we do not have to handle all the teams manually, for example using HTTP-basicAuth.
Popular solutions involve the usage of JWT-Tokens (https://jwt.io/).

Since our backend is written in go we can use for example these packages:

https://github.com/dgrijalva/jwt-go
https://github.com/appleboy/gin-jwt

Set up tests with gotest

Add configuration options for the app

https://pub.dev/packages/global_configuration

• Create it as asset, as assets/config/config.json
• add it to the .gitignore
• Provide an example in assets/config/config.json.example

extend the team model

allow for more

Add initialization mode to the backend

Currently the backend tries to initialize itself and the database everytime a new container is created.
This should be changed by adding an env var

make the csv mapping more robust

Currently the records are selected using fixed indexes, which is very error prune:

explorer-app/server/server.go

Lines 35 to 44 in c2884be

	func createStationFromSplice(db *gorm.DB, input []string) *gorm.DB {
	return db.Create(&model.Station{
	ID: getInt(input[0]),
	Points: getInt(input[1]),
	StationType: getInt(input[2]),
	Coordinates: &input[3],
	GridSquare: &input[4],
	Title: &input[5],
	})
	}

Enable verbose Database Logging in non Production mode

Sth like this

if ! os.Getenv("PRODUCTION") == "1" {
    return db.LogMode(true)
}
return db

Sketch out the views in the App

Submit correct answers to the Server

implement function to submit answers

This vhost also has to be set up for local dns i.e. `explorer.local`

This vhost also has to be set up for local dns i.e. explorer.local

Start using the BloC Pattern

https://github.com/felangel/bloc

Add Login Page within the App Settings

We need Page were the Groups put in their credentials. This value must be saved and later used for identification when the data is submitted.

Provide GraphQL Examples

When playing around with the examples in the GraphQL-Playground it always takes some time to get the examples again.
These should be included somewhere 😊

Create Deployment infrastructure for the Backend

For every manned station on the explorer there should be one possibility to sync up the current entries in the app.
Maybe this can be done using some Raspberry Pi's and a router?

The configuration of these should be uniform, preferably using a configuration tool like ansible-playbooks.

Decide on a DB framework

Since we also have to store the information from the quiz offline we should investigate some possibilities to have a "local" database in the app.
Maybe we can also used the types generated by artemis here 👍

Use correct logo for the app in the menu

Improve the look of the listitems & details page
