I got this weird error when developing flutter app in windows. I have set my local apache as my API server. When I tested my API in Postman, everything is okay. Error appears when I tested API on my app with emulator.
Turn out, the problem is from emulator. Android emulator can’t communicate with 127.0.0.01 or localhost. The solution is just change localhost to 10.0.2.2. This IP is special alias to your host loopback interface.

One of the most common thing I made in mobile development is login page. This project is boilerplate, template, or whatever you called, of basic login page. Made with Flutter.
It has standard 2 fields, username and password with toggle which can be clicked to show/hide password.
One of the problem I got as a flutter beginner is bottom overflowed by xx pixels. This problem would appear when virtual keyboard needs to be showed. Keyboard take half of our screen, if you done your layout wrong (like page that take more than half of screen), you will got bottom overflowed error.
The solution is use SingleChildScrollView in the top widget. So, when you got this error, you can scroll through our overflowed part of the page.

Real device deployment is way to go. But, sometimes dealing with USB cable is not pleasant experience. So, the solution is using WiFi to connect with my device.
