Flutter and Blockchain DAPPS
Hi there,
My name is Kartikey. I am an app developer studying in SRM Chennai 2nd year. Actually, from past couple of weeks, I was working on implementing blockchain in flutter and I came across your great article on medium about it but I am facing some errors in implementing web3dart in my project. I tried searching it on stack overflow , viewing all yt videos on it and talking to some people on linkedin about it but I found nothing to problems in my code
I checked your repositories and I found that I was using the same code but still getting problems in it. These are the following issues that I am facing
I was wondering if you could help me resolve these issues.Thanks in advance
