# MobileEventLog
A cross plattform project for android and ios to log events offline everywhere and sync them to sensor. Developed with flutter. A short how to use can be found below documentation/README.md
<br /> 
![Add a new Event](documentation/05_AddEvent.JPG)
<br />

## Concept
- Config page: Select the collection and get corresponding devices, all event types. Store all this to a local persistent configuraion. 
- Add Event Page: Allow selection of a device and adding a new event with all details. Add button adds the event to the staged events. Fields are not cleared but kept as they are. 
- Staged Event: Show all entered and not yet uploaded events. Allow modification of all fields here. Alternatively show all events including uploaded once.  

## Local Data Concept
- The configuration widget is used to get the online available information for available devices and event creation. 
- This includes: All collections, All devices part of a selected collection, Event operation types
- This "base data" is required to provide the dropdown menu options on the addevent page.  
- This "base data" is stored persistently, so that it is also available offline!

## Add Event Page
- Use Switch for automatic GNSS and Time update. 
- Show "now" time button only if GNSS is disabled. This button shall fill the timestamp with the current utc time.
- Add stores the event to a local sql database
- A slide switch activates GNSS locationing. A field shall signal the GNSS status "no fix" or "x m presision". The fields lat, long, elevation and timestamp are updated automatically if GNSS is enabled.
- Input validation is done according sensor.awi.de Free Text: "a-z , A-Z , _ , 0-9 , ,(Comma) , ( , ) , + , - , . , :"  -90 => Latitude <= +90  -180 => Longitude <= +180  Elevation: any numer

## View & Sync Page
- Events added on the addevent page are stored persistently (sql database). They can be displayed in the view
  events widget. Each event has a flag which shows if the event is already exported to sensor. A slide switch allowes to show all events?

## Configuration Page
- Switch to select if Mission or Collection based Or Own editable devices?
- Dropdown "Collection" to select a collection / mission
- Button "get Collection devices from Sensor"
- Button "store Collection devices locally"
- Select a Mission from the new Sensor-Mission-Management to get a set of devices.
- Username und passwort. "Test login on store even if  not required here"
- Functionality to export events locally for backup in the field! 


# TODOs
- Provide configuration instead of collection with: https://sensor.awi.de/rest/sensors/device/getEditableItemsOfContact/mobileeventlog.awi%40gmail.com 
- Allow logging of events also without sensor account. Everything except the upload back to sensor shall work. 
- Allow adding an event to more than one device (urn)!    "make UrnId => UrnIds"  sync a event to every listed urn.   ?  Really needed?
- Compile an Apple iOS version.
- On older Android 6 Devices the following error is shown"  OS Error CERTIFICATE_VERIFY_FAILED: certificate has expired".   Fix or require at least Android x? 
- Add Git Tags as version information and show in app.  
- Implement switch to select sandbox or productive version?

- Add Icon to Add, View and Configuration button. Then use uppercase Text. 

## Configuration
- Collection List Drop Down. Item separation "grey line"  +  Abbort button. "Highlight  "chosen collection" italic or pinned on top. Sort alphabetic.  
- Add a selection mode functionality. 1. Own devices (based on e-mail adress as editor on devices), 2. Collections, 3. Mission management based
- https://sandbox.sensor.awi.de/rest/sensors/device/getItemsOfContact/mbetz%40awi.de
- Split in two widgets? 1st to login und 2nd to configure. Allow configuration only with successfull login? 

## Add Event
- Show \* next to lable for required fields. 
- Event Type /URN   Item separation and hightlighting chosen type as in configuration.
- Label with counting up number? 
- Set in configuration: Label on Add Event is beeing cleared but GNSS data is not. Harmonize this.
- Decide if GNSS switch shall be moved next to lat long fields. Similar to the NOW field. 

## View & Events
- "All Events" "Pending Events" on first line above table. Alligned right.  50pix hight distance to table start.   
- Allow to remove pending event(s) or set them to "deleted"
- Feedback popup as in the other widgets. 

## Wishlist:
- Allow upload of pictures  check interface how to upload with sensor. 
- How to log events for a device which does not exist yet? Dummy device in app and assign befor upload? 
- Collection im Feld auswähle, Collection - Arbeitsgruppenzugehörigkeit. 
- URN  Dropdown filter by character.  ~500 Geräte Verankerungsgeräte. Mission Sub Subcollecction/ Submission z.B. Verankerung oder Eisarbeiten oder Bojen?   
- unique labels are desired by PANGAEA.  Is adding the MissionName as a prefix to label usfull? 
- Document taken sample via IGSN number QR Code? Scan a QR code.
