update();
}
}

//page
var p1 = Get.put(
Page1Controller(),
);

var p2 = Get.put(
Page1Controller(),
tag: 'a',
permanent: false,
);

...
GetBuilder(
init: p1,
builder: (_) {
return Column(
children: [
Text(p1.geti1.toString()),
ElevatedButton(
onPressed: () {
p1.seti1 = p1.geti1 + 1;
},
child: const Text('p1')),
],
);
}),
GetBuilder(
init: p2,
builder: (_) {
return Column(
children: [
Text(p2.geti1.toString()),
ElevatedButton(
onPressed: () {
p2.seti1 = p2.geti1 + 1;
},
child: const Text('p2')),
],
