Answer 1

Some times flutter clean works for me.

But When flutter clean does not work then I apply below technique:

I push my project to git repository(I used Bitbucket) and delete this existing project. Then pull my project from git repository and setup my project. After all my project working as usual.

Answer 2

Try flutter clean along with flutter channel master && flutter upgrade

Answer 3

Thanks @Md Mahmudul Islam. In my case one extra steps solved the issue smoothly.

-Flutter Clean

-Flutter upgrade [upgrade 1.17.2 to 1.17.4]

-Increase Android studio Heap memory :

Program Files->Android->Android Studio->bin->studio64.exe.vmoptions

Open the file and increase the value -Xmx1280m as you want. I changed -Xmx1280 to -Xmx2280

You can also see on bottom right corner, how much memory used in your program by enabling this

File->Settings->Appearance->check 'Show memory indicator'

Note : Try to upgrade Flutter on Latest stable version
