As native support of flutter into the AGL platform is being considered, there is already a way to run flutter applications on the existing demo platform, and have them using the available application framework.
In this document we will be describing the different components that are in place for both having native applications connecting to the available appFw apis, and to bundle flutter apps and run them as web applications with WAM.
There is an issue in JIRA tracking this work https://jira.automotivelinux.org/browse/SPEC-3876
The requirements for creating a wam widget are having a (zipped) package containing a XML configuration file. After adding a configuration file and creating a .wgt zipped package from flutter's build/web directory, it's possitble to install the application as a widget. The following widget was built using the flutter particle sample code:
