Values

device → const VariableScope

The variable is stored locally on the device's persistent media e.g SD card, disk, localstorage.

app → const VariableScope

State with this scope is available to all screens. Updating it on one screen will update it on all of them. In memory only.

static → const VariableScope

State with this scope is available to all screens. Updating it on one screen will update it on all of them. In memory only.

screen → const VariableScope

State with this scope is available only on the screen where it is declared, therefore two screens that have a variable with the same name are independent and updating it one one screen does not update it on the other. In memory only.
