Flashlight not working on Android

[AlexBacich]

Flash isn't working. Tried to start on example - it gives an error:

I have tried to make the example code work on a Nexus 5 running Nougat (7.1.2) without any luck. I have granted my application permissions to use the camera without affecting the outcome. The flash is working as I can toggle it from the dropdown menu. However, when I run it on a Oneplus5 with Oreo I can make it work. Has anybody else encountered a similar problem?

The only outcome I get in the terminal is the initial check: I/flutter (16233): Device has flash ? true

I have specified version lamp: 0.0.6 as dependency.

If you need a solution now, look at Issue #7 and follow use of torch.zip plugin.

I tried to make it work without any luck. I will try to document my steps to figure out where I went wrong. Thanks for the reply.

Just a thought: have you considered closing this issue?

I haven't closed this issue as, even though I've worked around it, it is still an issue with this package (flutter_lamp).
