I just reviewed the newest mobile development sdk by google called "Flutter". It looks like the same concept of accomplishing an app for introducing their "widgets" while in xojo is container.
Like XOJO, no need to learn HTML and CSS needed too. How ever there is no DRAG N DROP to create screen design. All screen are design thru hard code.
As of now, It can produce native ios and android app and soon availble in desktop and web too.
Look like its a treat to XOJO? Any thought from you guys?
