我想知道如何删除默认边距 Flutter Slider

                    Positioned(
                      child: Align(
                        alignment: Alignment.bottomLeft,
                        child: SliderTheme(
                            data: SliderTheme.of(context).copyWith(
                              trackHeight: 2.0,
                              thumbColor: Colors.transparent,
                              thumbShape: RoundSliderThumbShape(enabledThumbRadius: 0.0),
                            ),
                            child: Container(
                                width: 380.0,
                                height: 20.0,
                                padding: EdgeInsets.all(0.0),
                                decoration: BoxDecoration(
                                  border: Border.all(color: Colors.blueAccent)
                                ),
                                child: Slider(
                                  value: 50,
                                  min: 1,
                                  max: 100,
                                  divisions: 100,
                                  activeColor: colors.primaryRed,
                                  inactiveColor: Colors.white,
                                  onChanged: (double newValue) {
                                    print(newValue);
                                  },
                                )
                            )
                        ),
                      ),
