Working theory

A happy healthy body, will aid with learning.

Features

Build ipa

• increment build or major version
• create ipa

flutter build ipa

• open ipa, validate and distribute

open  build/ios/archive/Humble\ Plank.xcarchive

Development

learnalist-openapi-dart

This comes from generating dart client library for learnalist.net.

To update

• Clone http://github.com/freshteapot/learnalist-api/
• Generate openapi for dart

make generate-openapi-dart

• Copy to this app

cp -r /tmp/openapi/dart/ learnalist-openapi-dart

• Due to bug, we need to replace in learnalist-openapi-dart/lib/model/http_asset_upload_request_body.dart

In HttpAssetUploadRequestBody.fromJson

    file = (json['file'] == null)
        ? null
        : MultipartFile.fromString("file", json['file']);

Getting secrets

mkdir -p ~/git/secrets/thehumbleplank/android/app

mkdir -p ~/git/secrets/thehumbleplank/android/app/google-services.json
cp ~/git/secrets/thehumbleplank/android/app/google-services.json android/app/google-services.json

cp ~/git/secrets/ios-thehumbleplank-GoogleService-Info.plist ios/Runner/GoogleService-Info.plist

Sign the app for android

keytool -genkey -v -keystore ~/git/secrets/the_humble_plank_key.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias the_humble_plank_key

cp ~/git/secrets/android-key.properties android/key.properties

keytool -list -v \
-alias the_humble_plank_key -keystore ~/git/secrets/the_humble_plank_key.jks

Create feature icon from play icon

convert assets/icon/android-play-icon.png -gravity center \
    -background white \
    -compress jpeg \
    -extent 1024x500 assets/icon/android-play-feature-graphic.png

Deploy android

• Need to use x86_64 in your emulator (changeable after the fact)

ANDROID_HOME=/Users/tinkerbell/Library/Android/sdk \
bundletool build-apks \
--bundle=build/app/outputs/bundle/release/app-release.aab \
--output=/tmp/the-humble-app.apks \
--ks=~/git/secrets/the_humble_plank_key.jks \
--ks-key-alias=the_humble_plank_key \
--overwrite \
--device-spec=/tmp/device-spec.json

bundletool install-apks --apks=/tmp/the-humble-app.apks
