For non-rooted Android devices, CA certificates can only be installed in the user directory. However, after Android 7.0, the client cannot trust the CA certificate in the user directory, resulting in SSL handshake failure. So, how to solve this problem?

Reqable desktop app uses the system network proxy to capture traffic, but it has limitations. For example, some applications or network libraries ignore the system network proxy settings and the traffic does not go through Reqable. In this case, Proxifier is needed. This article specifically introduces how to use Proxifier and Reqable to solve this issue.

Flutter uses Dart as thed evelopment language, but Dart SDK is not proxy-aware, which means the application doesn’t use the proxy configuration of the system and sends the data directly to the server. We usually set up a network proxy for Wi-Fi to intercept the traffic. Obviously, this does not work for the Flutter application.
