How do I build different versions of my Flutter app for qa/dev/prod?

Question

I am building a Flutter app, and I have variables with different values for different environments (QA, dev, prod, etc). What\'s a good way to organize my app so I can easil

Answer 1

Release and debug mode can now be acquired using

const bool isProduction = bool.fromEnvironment('dart.vm.product');

Because this is a constant it works with tree-shaking.
So code like

if(isProduction) {
  // branch 1
} else {
  // branch 2
}

would only include one of these two branches into production code depending on isProduction
