I have recently upgraded to flutter v3, and I am seeing this message Flutter Web Bootstrap: Auto, sometimes Flutter Web Bootstrap: Programmatic in my debug console. I did search for it but the results returned with bootstrap implementation for flutter. I am not sure but I think it is related to how the app should load in flutter web. I want to know in depth what this means.
Before flutter 3.0 we have one automatic bootstrap strategy. Flutter 3.0 gives us more control on bootstraping (for example you may add some visualizaton during flutter initialization) so called programmatic strategy.
