this is my code

                          await _cameraController.startVideoRecording();
                          setState(() {
                            startTimer();
                            isRecoring = true;
                          });
                        },
                        onLongPressUp: () async {
                          final videoPath = await _cameraController.stopVideoRecording();
                          setState(() {
                            isRecoring = false;
                          });
                          print("Going to next screen");
                          Navigator.push(
                              context,
                              MaterialPageRoute(
                                  builder: (builder) => VideoViewPage(
                                    path: videoPath.path,
                                    isWelcome: widget.isWelcome,
                                  ))
                          );
                        },
                        child: isRecoring
                            ? Icon(
                          Icons.brightness_1_rounded,
                          color: Colors.red,
                          size: 120,
                        )
                            : Icon(
                          Icons.panorama_fish_eye,
                          color: Colors.white,
                          size: 70,
                        ),
                      ),

all I want is that If my timer function which is initialize after onLongPress() is == 60 then onLongPressUp() method call.Please help me to solve this problem. Thanks in advance.

CodePudding user response：

Perhaps with the following code in your GestureDetector:

onLongPressDown: () {timeLongPressStart = DateTime.fromMillisecondsSinceEpoch(DateTime.now())}

onLongPressUp: () {
    timeLongPressEnd = DateTime.fromMillisecondsSinceEpoch(DateTime.now())
    if (timeLongPressEnd - timeLongPressStart < 60000) 
    {
        Do your logic
    }
}

CodePudding user response：

Please check the following codes

import 'dart:async'; onLongPress(){ Timer(Duration(seconds: 30), () { // your logic here // });}

Another way is:

onPressed: (){Future.delayed(Duration(seconds: 5), () { // your code here //});},
