setstate futurebuilder flutter

Solved!

I am getting date from FireBase via a futurebuilder.

It returns a Row whose children is a list of a widget i created called SmallDogCard (since my app is about dogs).

On a screen i want users to be able to press on the SmallDogCard to select it and change the border color, howerver. This causes the futurebuilder to load the data again... How should i approach this?

My code:

Futurebuilder:

FutureBuilder(
                                future: DogOwnerModel().getUserData(),
                                builder: (context, snapshot) {
                                  if (snapshot.hasError) {
                                    return Text('error');
                                  }
                                  if (snapshot.connectionState ==
                                      ConnectionState.done) {
                                    List<SmallDogCard> dogCardList = [];
                                    final userData =
                                        snapshot.data as Map<String, dynamic>;

                                    List<Map<String, dynamic>>? userDogs =
                                        userData['user dog data'];
                                    if (userDogs == null) {
                                      return Text('no dogs yet');
                                    } else {
                                      for (Map<String, dynamic> dog
                                          in userDogs) {
                                        dogCardList.add(SmallDogCard(
                                            dogName: dog['name'],
                                            imageUrl: dog['profile image'],
                                            isSelected: selectedDogs
                                                    .contains(dog['name'])
                                                ? true
                                                : false,
                                            selectCallback: selectDogCallback));
                                      }
                                      return Row(
                                          mainAxisAlignment:
                                              MainAxisAlignment.start,
                                          children: dogCardList);
                                    }
                                  }
                                  return Text('Loading');
                                },
                              ),

Onpress function callback passed to the SmallDogCard (which uses setstate and makes the futurbuilder get the data again).

selectDogCallback(String name, bool isSelected) {
    if (isSelected == false) {
      selectedDogs.add(name);
    } else {
      selectedDogs.remove(name);
    }
    setState(() {
      selectedDogs;
    });
  }

How can i accomplish this without the futurebuilder being called again? So i can setstate which changes the border color of the SmallDogCard which is returned from the FutureBuilder.

Thank you in advance!

Problem solved!

Initializing the future in initstate, so after initstate it wont be called again!

Like this:

      @override
  void initState() {
    // TODO: implement initState
    super.initState();
    _future = setFuture();
  }

  setFuture() async {
    return await DogOwnerModel().getUserData(email: email);
  }
