Session Storage

Flet provides an API for storing key-value data in user's session on a server side.

Caution

In the current Flet implementation the data stored in a session store is transient and is not preserved between app restarts.

Write data

# strings
page.session.store.set("key", "value")

# numbers
page.session.store.set("number.setting", 12345)

# booleans
page.session.store.set("bool_setting", True)

# lists
page.session.store.set("favorite_colors", ["red", "green", "blue"])

Read data

# The value is automatically converted back to the original type
value = page.session.store.get("key")

colors = page.session.store.get("favorite_colors")
# colors = ["red", "green", "blue"]

Check key existence

page.session.store.contains_key("key") # True if the key exists

Get all keys

page.session.store.get_keys()

Remove data by key

page.session.store.remove("key")

Clear all data

page.session.store.clear()
