DAO Opener

A new Flutter project.

Getting Started

FlutterFlow projects are built to run on the Flutter stable release.

IOS FlutterFlow issue

• FlutterFlow/flutterflow-issues#1766
• com.fifithpint.daoopener.imageNotification

Polygon SDK Surprises

• No emulator support
• Known memory leak, so recommend beefier phones
• No news is good news. If there isn't a error thrown, keep going. No return codes.

Other Notes:

• Really need to have approved sets of tools that are known compatible. Solution kits. GCP lagging a month is a dealbreaker when things are moving fast.
• URL Schema vs LD Schema consistency across apps with error checking is a must.

FlutterFlow Sync problems

• IOS losing config settings and requiringn workaround
• ImageNotification Signing Settings - select team from Xcode
• Build Phases reorder to avoid bug (Anything with Embed has to go before copy scripts)
• All the Firebase functions since their functions were too restrictive to use.

Passkit Generator - Firebase example

• https://github.com/alexandercerutti/passkit-generator/tree/master/examples/firebase

Building App

• flutter pub get

Building Firebase Functions

• cd functions
• npm install
• firebase deploy --only functions
