Hi @maciogg
Just tried on ios on the latest stable plugins as seen your plugins logs

[+20991 ms] flutter: onResume: {id: 1, google.c.a.c_id: 9212739073003242153, gcm.n.e: 1, google.c.a.e: 1, gcm.message_id:
1604409599880144, google.c.sender.id: 486685679562, gcm.notification.sound2: default, google.c.a.udt: 0, google.c.a.ts:
1604409599, aps: {mutable-content: 1, alert: {title: Test, body: This is a test}, badge: 1, sound: default}, click_action:
FLUTTER_NOTIFICATION_CLICK, status: done}

onResume is only called when you tap on the notification and never got called when in background on the latest stable flutter channel

flutter doctor -v
