>Solution :
You overlook something. Try like this please.
{getBanks.map((bank, index) => (
<Picker.Item
label={bank.name}
value={bank.code}
key={index}
/>
))}
UPDATE
Define a state variable to track the selected bank
const [selectedBank, setSelectedBank] = useState();
Modify your Picker element like that
<Picker
selectedValue={selectedBank}
onValueChange={(value, index) => setSelectedBank(value)}>
{getBanks.map((bank, index) => (
<Picker.Item
label={bank.name}
value={bank.code}
key={index}
/>
))}
</Picker>
