3 months ago By the way, if it delays the breakpoint a bit before building, It works fine.

3 months ago It definitely works the first time. The second time it doesn't.

3 months ago I used startDelay: true and it worked fine.
We are creating a new instance and outputting it as an independent Widget View, not a PageView.
Is this the right way to use it?
Thank you.
[My code]
Scaffold(
body: SafeArea(
child: Stack(
children: [
/// scanner
MobileScanner(
controller: MobileScannerController(formats: [BarcodeFormat.qrCode]),
startDelay: true, // <-- new flag
onDetect: (BarcodeCapture barcodes) {
if (detectedCode != null) {
return;
}
if (barcodes.barcodes.isNotEmpty) {
detectedCode = barcodes.barcodes[0].rawValue ?? '';
if (widget.onDetect != null) {
widget.onDetect!(detectedCode);
}
pop();
}
},
scanWindow: scanWindow,
),
/// scanner overlay
RepaintBoundary(
child: CustomPaint(
painter: _ScannerOverlay(
scanWindow: scanWindow,
color: widget.themeColor,
radius: widget.viewFinderRadius,
strokeWidth: widget.viewFinderStrokeWidth,
canScanLine: widget.canScanLine,
scanLineColor: widget.scanLineColor,
scanLineStrokeWidth: widget.scanLineStrokeWidth,
),
),
),
/// overlay Widget
widget.overlayWidget,
],
),
),
);Is there any way to handle startDelay: true when the camera is shut down, not when it starts up? If it could be pre-initialized, it would be a little faster on the next run.
Thank you.

3 months ago This seems to be related? https://github.com/flutter/flutter/issues/138947
The issue seems to be fixed on the master channel at the moment, so this will be included in the next Flutter stable release, that is due sometime this month. If you switch to the master channel, does the issue occur?

3 months ago Is 'startDelay: true' just a time delay? Is it 1.5s? It certainly seems like a long time, is there a reason?
if (widget.startDelay) {
await Future.delayed(const Duration(seconds: 1, milliseconds: 500));
}This seems to be related? flutter/flutter#138947

I haven't checked the github master version yet. I'll check the master version or wait for the next patch.
Thank you.

3 months ago The start delay is an older parameter that was left in from older releases.
It will be removed in the next major release.

I've verified that it works on the master version. Hopefully it will work with the next update.
Thanks a lot.

Hi,
An error occurs on the Android device. The first time you run the camera, there is no error, but the second time, there is an error.
This hadn't happened before. This is a recent error.
Why is this error occurring?
