🐛 Fixing Import/Export Bugs for Rules & DNS
🧩 Fixed duplicate presets that wouldn't die: Problem: When exporting a rule file, presets like "Traffic processing" and "Block ads" (which contain sniff and hijack-dns settings) were included. After import, a second copy of the same preset was created that could not be removed – deleting one left the other, and deleting both brought one back. Cause: These presets must always be the first entry in route.rules so the domain is extracted before routing matches. The app re‑creates the preset whenever missing, checking by preset id – two copies satisfied the check, none triggered a re‑seed. Fix: Presets are no longer part of export/import, as they're built‑in templates everyone already has. This mirrors the decision for DNS presets. Duplicated lists auto‑repair on opening the Routing screen (extra copy removed, keeping the last imported one – the more recent intent). Deleting a preset still brings it back only if it was the only copy.
🚫 No more duplicate names in rules: Previously, importing a rule with an already‑taken name added "(2)" suffix, making it hard to distinguish and clean up. Now the duplicate is rejected entirely – the row is greyed out as "Already on this device" and its checkbox disabled. This also applies to two same‑named rules in one file.
📤 Export DNS independently without requiring a rule selection: The Continue button on the first export step no longer requires a rule selection. Leave everything unticked, go to Include DNS, pick your servers and DNS rules – the file carries only those. If nothing is selected anywhere, the Export button stays disabled (no empty files).
✅ Tests: All 3051 unit tests, flutter analyze, and all 6 l10n checkers pass. The duplicate preset fix was verified on an emulator using the same storage that produced the bug report – it collapsed to one on first screen open, presets no longer appear in export picker, and Continue works with nothing selected.
