onPressed: () {

},
)
],
)
),
),
...
The username works properly, but the password field loses its focus after I enter a first letter. If the obscure set to false, it works properly.
I thought that it is because of the Flutter Build. I find this issue in my old laptop, and when I use my new laptop to build the FLutter app first time, it works properly, but after a lot of build in the same laptop, the issue is appearing again. So I tried to clear all the build, Flutter Build, and .graddle, I also tried to clean pub cache and rebuild it. But the issue persists.
Can anyone let me know what is the main cause of this issue? Thank you...

Reset to default 0I have two answers for this, I hope it helps.
In your input.dart your input border it is relay on property
param.withBorder, in your case make sure to put it to trueIn your input.dart you set the container height with
param.size?.height ?? 48and in your login file you create input into a Container with height only 43, logically you may put the height of container in login file at least 49.
