Troubleshooting

Changing "system" files

If you modify AndroidManifest.xml or Plist.info or something, you need to hard reboot the emulator; run flutter clean && flutter pub get; and then rebuild. There's tons of cache in tons of different places that gets replaced in tons of different ways.

Setup

This client uses Flutter to support frontends on iOS, Android, and web.

Install Flutter

https://docs.flutter.dev/get-started/install/macos

Fix platform dependencies

flutter doctor

Setup vim Flutter and Dart plugins

  1. https://github.com/dart-lang/dart-vim-plugin
  2. https://github.com/thosakwe/vim-flutter

Init project

flutter create .

Init FlutterFire

This lets us attach to Firebase. First, make sure you've got a non-system Ruby and cocoapods installed. Next, run the following, reproduced here verbatim from the fireflutter docs:

# Install the CLI if not already done so
dart pub global activate flutterfire_cli

# Run the `configure` command, select a Firebase project and platforms
flutterfire configure

This will generate lib/firebase_options.dart.

Install cocoapods

The flutterfire configure will barf unless you install xcodeproj beforehand:

gem install xcodeproj cocoapods

Install your own Ruby

Don't use system Ruby, that's a no-no.

  1. brew install ruby
  2. Update the path env var to have /usr/local/opt/ruby/bin
  3. Update the path env var to have (gem environment gemdir)/bin

Run

ios

open -a Simulator
flutter run

Dev

Environment variables

Configure via command pallete -> launch.json in vscode.

configure access to moshi-srv host

  • MPROTOCOL default https
  • MSERVER default dev.chatmoshi.com
  • MPORT default 443

configure dev emulators

If in debug (non-release) build mode,

  • MREMOTEAUTH default false i.e. use emulator
  • MREMOTEFIRESTORE default false i.e. use emulator

Android emulator

  • Enable virtual microphone uses host audio input in the 'Microphone' submenu of the '...' expandable in the emulator toolbar. Otherwise the emulator mic will pick up only silence (static).

On write in vim, hot reload flutter

In vim, :FlutterRun -d chrome

Code organization

Changes to permissions

ios

Add the tag to ios/Runner/Info.plist. Add the PERMISSION_ declaration in ios/Podfile.

Clear the Xcode build files so the new permissions get propagated:

flutter clean

Release

Android

iPhone
