Flutter tips and tricks

" summary

Avoid async code in main; move startup into a Future (e.g. loadApp) and provide multiple entry points like main_prod to handle startup errors and restore or clear state. Use deferFirstFrame / allowFirstFrame to keep the native splash and prevent flicker while precaching assets. Don’t call async work during build — lift streams out (or use a stream_create_builder) so StreamBuilder gets a stable stream. Prefer mediaQuery.sizeOf / inherited model to reduce rebuilds, use AspectRatio instead of LayoutBuilder when possible, and use IntrinsicWidth for equal buttons.
