Erro ao rodar o script

[julioffigueiredo]

Tenho o seguinte comando no yaml:

Edit: ficou sem endentação o código do yaml abaixo, os nomes de scripts começam com avanço de 2 espaços!

`slidy: '1'
variables:
customMessage: "Complete"

scripts:
mobxd: fvm flutter pub run build_runner watch --delete-conflicting-outputs
mobxw: fvm flutter pub run build_runner watch`

E ao rodar o comando slidy run mobxd/mobxw me retorna:
