Fails: flutter packages pub run build_runner build

[hoek]

Hi,

anyone know what to do about this failing:

$flutter packages pub run build_runner build

?

Maybe update some tool?

Thanks for any and all help.

If you are using json_serialize just update it to

json_serializable: ^2.0.2

    if not then update the other dev dependicies to the lastest version it solves the problem.

[Steven McDowall]

Btw - with the latest upgrade there are a lot of package upgrades that need to be done manually due to how semvar works .. 

So make sure to look at your pubspec and go and check the latest versions .. many have the 0.x number changed that is not reflected in a flutter upgrade

Just a heads up
