How to make a circle shaped tab indicator in flutter

Question

I need to have 4 tabs with 4 circles at the bottom indicating which tab you are currently on. Like this. I cant make it just a Row with 4 containers changing colors, i need them to be fully functional buttons where i can switch between tabs when pressing them. My main problem is that i can't seem to make my tabs narrower, and they end up being about 30 pixels apart, which is not what i want. Any help is appreciated. Here is my code so far

Container(
                      width: 22.0.h,
                      child: TabBar(
                        indicatorPadding: EdgeInsets.zero,
                        indicatorSize: TabBarIndicatorSize.label,
                        tabs: [
                          Tab(
                            child: Container(
                              height: 1.0.h,
                              width: 1.0.h,
                              decoration:
                                  BoxDecoration(color: UIThemes.buttonDarkBlue, shape: BoxShape.circle),
                            ),
                          ),
                          Tab(
                            child: Container(
                              height: 1.0.h,
                              width: 1.0.h,
                              decoration:
                                  BoxDecoration(color: UIThemes.buttonDarkBlue),
                            ),
                          ),
                          Tab(
                            child: Container(
                              height: 1.0.h,
                              width: 1.0.h,
                              decoration:
                                  BoxDecoration(color: UIThemes.buttonDarkBlue),
                            ),
                          ),
                          Tab(
                            child: Container(
                              height: 1.0.h,
                              width: 1.0.h,
                              decoration:
                                  BoxDecoration(color: UIThemes.buttonDarkBlue),
                            ),
                          ),
                        ],
                      ),
                    ),
