Flutter is declarative, in that: UI = F(state). UI is a function of state.
If you want to lock something in the UI, set a state variable to indicate this and have the UI respond to this.
More specifically, for instance set a
isLoadingstyle state variable (be it through a stateful widgetssetStateor a state management approach, e.g. Provider) when your API call starts and then set it back to false once the API call ends. In your UI then have the UI block either the whole page, or the button in question, if that state variableisLoading == true
