'value >= min && value <= max': is not true - flutter

my music player is playing the first file totally fine, but when switching to the next song, it shows this error:

'package:flutter/src/material/slider.dart': Failed assertion: line 132 pos 15: 'value >= min && value <= max': is not true.

the values I'm sending to slider are not going to be negative or even null, I'm sending values this way:

          Slider(
                  value: _duration != null
                      ? _duration > defdur
                          ? _position?.inMilliseconds?.toDouble() ?? 0.0
                          : 0.0
                      : 0.0,
                  onChanged: (double value) {
                    return audioPlayer.seek((value / 1000).roundToDouble());
                  },
                  min: 0.0,
                  max: _duration != null
                      ? _duration > defdur
                          ? _duration.inMilliseconds.toDouble()
                          : 0.0
                      : 0.0),

the defdur is default duration i made like this: 

var defdur = Duration(milliseconds: 0);

so basically i have two inline if statements, for checking if value is null or not bigger than 1 milliseconds, return 0 and still problem occurs!

I think the minimum Max value of Flutter Sliders is 20, keep the max value 20 or greater than 20, simply add a condition if value < 20 ? 20 : value

Slider(
    min: 0,
    max: value.toInt() < 20 ? 20 : value,
    value: _value,
    onChanged: (value) {}
)

Just Move the min and max properties in between the value property and the onChanged function will looks like the following :

value : yourValue,
min:0.0,
max: 1.0,
onChanged: (double NewValue){
 //YOUR CODE
}

Just increase 1 to the max parameter, Because, for example, some audio clips have their real time 4:00:01, and therefore this number is already greater than 4:00:00

Try this:

return audioPlayer.seek((value / 1000).roundToDouble().round());
