Hi Damlers,
Am asking if there is anyone on the forum who is using or has used within the past year, either of Googles’ UI development tools, Flutter or Dart to make Desktop/Mobile apps or other UIs?
My plan is to use Flutter as a UI for a simple Smart Contract.
Tips, hints or comments welcome.
Would love to hear your experience and if there’s anything we can learn or improve in Daml from that experience.
I have used Flutter but not with DAML which is what I guess you are after.
I actually have a similar question and that is regarding the use of JavaFX for the UI layer.
DAML recommends React as part of its UI stack component but the little that I know is that apparently the gateway is thru a JSON/RPC gateway so perhaps one doesn’t need direct support. Flutter does have a JS integration package i.e. which should allow one to tap into the DAML React libs.
I do like Flutter but for this scenario I would probably in my case prefer to use JavaFX and thus my question is whether the DAML Java bindings are sufficiently complete as the React bindings. For example, is there a full blown ledger API available from the Java bindings that I could therefore tap into from a JavaFX/Groovy UI ?
Will do. The first goal is to make a Desktop UI that allows the executing of a Linux command. If/when I can do that, I will target the Daml REPL. As I have never used any sort of UI framework before and are slowing working through the Daml_SDK docs, this might take a while.
I have been talking to some UI experts from Flutter and other languages, and the biggest hurdle is ‘what do you want to do’?
Think more on this, I will.
I use Flutter and a GraphQL backend for one of my projects but haven’t tried with a Daml ledger just yet. For a Daml ledger I’d probably try to use the gRPC API (gRPC — Daml SDK 1.11.1 documentation) together with Darts gRPC library (Quick start | Dart | gRPC).
Thank you for the reply, I will read through these links 
The Java gRPC bindings should actually be more complete than the React bindings. There are use-cases you can support through a JavaFX UI that you could not (easily) support with the React bindings.
Easily here means “without implementing your own gRPC <-> HTTP mapping layer”.
Gary,
that’s very interesting and comforting 
, we do like JavaFX quite a bit and even deployment on browsers via JPRO make it even more of a correct approach for us, thanks for the feedback
Hi @SteveSeow Any chance that you might consider a Flutter & Dart UI series of tutorials if there was sufficient interest?
I thought that the video you did for the Hackathon, while brief, was exciting. That entire UI SDK has extensive capabilities, especially with the Google ecosystem interoperability.
I’d be interested.
