Implements a basic scaffold for sending ZEC.
Some new model objects and an extension method were added that I hope to move to the SDK.
Followup issues include
- Press-and-hold for the Send button #249
- Prevent illegal input in input form #218
- Prevent undefined behavior if locale changes #217
- Add error handling to the Zec send screen #250
- Add confirmation after send is created #252
Test Orchestrator must be enabled, so that screenshot generation can walk through the app like a newly registered user. The screenshots are stored outside of the app's storage directory, so that Test Orchestrator does not delete them. Because hard-coded paths are used, it is possible this could be brittle with future versions of Android
A future enhancement would be to also copy these screenshots off of tests run on Firebase Test Lab. This would likely involve configuring Fladle/Flank with additional directories to pull.
In addition to the UI, this implements improved state management for the WalletViewModel which emits a sealed class now.
Work remaining for followup PRs:
- Use drag-and-drop for chips instead of dropdown menus #85
- Add red background color for test fail screen #86
- Add images for various screens (depends on #66#64)
- Implement copy to clipboard #49
