FBP Go (Fire Behaviour Prediction on the Go)
Fire behavior prediction application
Preview latest PWA build on: https://sybrand.github.io/
Build for web
flutter build web --base-href /MyBaseFolder/
Build
Update pubspec.yaml with the the correct version number.
Build for Android
Maybe you want to update first?
I have my android studio install in ~/.local/android-studio - with a symlink in ~/.local/bin/studio.sh
studio.sh
then System Settings -> Updates -> Check now If it fails because it can't update java - exit - check for java processes and kill them
ps -A |grep jav
kill -9 PID
flutter upgrade
Update the build in: android/local.properties e.g.:
sdk.dir=/home/[username]]/Android/Sdk
flutter.sdk=/home/[username]/snap/flutter/common/flutter
flutter.buildMode=release
flutter.versionName=1.0.1
flutter.versionCode=3
Up the version in pubspec.yaml, then run
flutter pub get
NOTE: also had to up flutterVersionCode in android\app\build.gradle
Make sure you have a way to sign it! You need to have your upload-keystore.jks configured in android/key.properties
flutter build appbundle --release
Head over to the play store - https://play.google.com/console/developers
select app internal testing -> create new release -> upload relesases overview -> review it
Build for iOS - on M1 silicon
If you use the default ruby+gem setup that comes out of the box, you'll get errors about ffi not being x86_64 - you COULD fix that by running:
# don't do this
sudo arch -x86_64 gem install ffi
Who wants to run rosetta? That's nuts. Rather get the latest version of ruby and go from there. (It's no use trying to run gem update --system with the system ruby, it's just going to break things for you) This also solves having to run sudo with gem, everything neatly goes into .rbenv
rbenv install 3.1.0
rbenv global 3.1.0
gem update --system
gem install cocoapods

For rbenv you need to have the shim in your path.

App store issues
You may receive an email warning: "ITMS-90078: Missing Push Notification Entitlement" from the app store. FBP Go doesn't use push notifications, it seems to be a side efffect of some flutter stuff. See: flutter/flutter#9984 ; this issue is unresolved at this point in time.
iOS development notes
open -a Simulator
open ios/Runner.xcworkspace
Deploy to app store
Make sure you've got the build number correct! Build number must be unique!

Code Conventions
- Dart naming convention rules are often broken in order to conform with the CFFDRS R library. The R code has been manually translated, and in order to debug and stay up to date with changes, it's just easier if the code looks similar.
Todo
- Change input values to match display (rounding on display, but not on input, can result in what appears to be inconsistent results). Different users are seeing the same input values, but in the backround they are different - as rounded values are being displayed.
- Add FWI.
- Grey out the curing slider for fuel types it doesn't apply to. (non-grass fuel types)
- Add screenshots for iOS.
- Localization - implement en-CA and fr-CA.
- Coordinates - provide user feedback on location button. (e.g. fetching and failed state).
- Add FMC option in advanced.
- Advanced: Problem: pre-set can conflict with entered values. The moment. anything is changed, the pre-set should become un-set OR You need a "load preset" button - maybe that's better?
- Advanced: Result columns - there are some "two line" columns. Would be nice if the result columns could size better.
- FFMC scale at the bottom.
- Possible, but nothing out of the box - so leaving it alone for now.
- Finalise disclaimer popup.
- Diurnal FFMC screen.
- Add a screen where you can input yesterday's FFMC the RH and the Wind, to get the daily FFMC - see: ffmcCalc.
- Add a screen where you you can see the impact of the diurnal FFMC (maybe sliding time?) - see: hffmc.
- Work towards a screen where you can see the impact of changing FFMC on fire.
- Do lots of re-factoring (code was written as p.o.c. in a big rush).
- Persist last settings? (Except for lat/long - since that's a log of the persons location and we don't want to persist anything personal)
- (pending p.o.) set the FFMC lower limit to 60?
- Add reference content to the Nav - e.g. pictures of the fuel types (trees) a la red book - would be great for newer folks; Easy to do, but needs images that we have licenes for.
- Request: group the data differently, especially in the advanced tab Work with EK to refine, general idea is to group info by: Head of Fire - Flank of Fire - ROS - CFB - … Back of Fire - ROS - CFB - … So folks can isolate and easily scan the info. They also find it too jumbled and tight and are worried they’ll grab the wrong numbers - Tess can help with that part (layout, sizing, spacing)
- crowning in grass isn’t possible - is there a bug? (bug in original CFFDRS library - we'll have to fix in our copy)
- User feedback/request: can we have pre-sets based on task? (Future idea) You open the app, say what you’re doing (prescribed burn, small fire, big fire/incident action plan, no fire just out and about - this is not the actual list) Prescribed burning: I don’t need all this info, reduce the list of data (maybe I can still personalize?) I wouldn’t care about the consumption of the flank in this case, and I better not be causing a crown fire
- If I’m manually inputting lat/long how do I do -122? Am I dumb? Is lat/long factored into the calcs? I was following along with EK’s demo and I got slightly different numbers from him for CFB, HFI, ROS (many users also reported this) - I can sent you a screenshot of EK’s screen for cross reference
- From testing session: users report difficulty with the sliders in terms of precision - hard to get the exact number they want. Sometimes this is ok, sometimes it’s very bad. Either way, it’s frustrating. Users pointed out that in the field their hands will be sweaty and dirty. Some folks realized they could turn their phone to landscape mode and it was a bit better. User-feature request: in addition to the sliders, can we have + and - buttons There may be other ways, UX can collaborate
- I can’t make the number pad go away after modifying location (lat/long/elev) - I have to re-select my fuel type to make it go away, not evident & annoying (from testing session w users) - seems to not be an issue on Android
Log of changes & decisions.
v1.0.2:
- Change keyboard type to all for negative numbers.
- Prompting for location permissions if not already granted on iOS. (Android should already be working)
- Wind + BUI sliders modified - users find it difficult to make small adjustments, resulting in inconsistent results.
- Changed wind slider to increment in 1's. (was in 1/2's!)
- Changed the BUI slider to increment in 5's. (was in 1's)
- Added line break to Beaufort scale 1-5 description (text was going off screen on small phones).
v1.0.1:
- Beaufort Scale now showing when selecting wind speed.
- Increased slider width, reduced label width and put line break between label and value.
- Added check for invalid latitude and longitude (was causing exception)
- Advanced+Basic: Moved curing from 2nd to last, to last.
- Advanced: Change PDF and PC to sliders.
- Advanced+Basic: Prompting for location permissions if not already granted. (Implemented and test for Android, iOS testing outstanding.)
- Changed icon for iOS.
- Added crown fraction burned to basic screen.
- More space on left hand side.
- Added padding on the left and the right.
- FFMC scale from 80+
- Made the scale start at 80.
- Fuel type picture.
- Added fuel type pictures, but request for licensed images resulted in pictures being removed for now.
- Coordinate affects FMC (it may not seem to for some part of the year), so we are keeping coordinates instead of using some default.
- App name: decided to call it FBP Go.
- Changed default flutter icon to fire emoji:
🔥 - Colour of output text and background changes to match severity.
- Reduced length of preset fire type names.
- Added disclaimer popup with placeholder text.
