Asset Filter Logic Documentation

Overview

This document describes the implementation of asset filtering logic in the TronLink wallet, specifically focusing on the interaction between basic mode, security anti-fraud reminder mode, and asset display settings.

Core Components

1. Filter States

  • hideLittleAssets: Controls whether to hide small value assets
  • hideScamToken: Controls whether to hide scam tokens

2. Mode States

  • isBasicMode: Indicates if the wallet is in basic mode
  • isAntiCheatOpen: Indicates if security anti-fraud reminder is enabled

Implementation Details

Filter Status Management

Reading Filter Status

The readHideLittleAssetsFlag() method handles the initialization and updates of filter states: 1. Retrieves saved filter settings from storage 2. Gets current mode status 3. Updates filter states based on mode status 4. Updates UI to reflect current filter states

Filter State Updates

The updateFiltersState() method manages filter state logic: 1. In basic mode: - Forces hideLittleAssets to false - Ignores saved small assets hiding setting 2. In non-basic mode: - Uses saved hideLittleAssets setting 3. For scam token filtering: - Only applies when anti-fraud reminder is enabled - Uses saved hideScamToken setting

Mode Change Handling

Basic Mode Changes

When basic mode is enabled: 1. Switches to user-defined sorting if currently using value-based sorting 2. Updates filter states 3. Refreshes UI

Anti-Fraud Mode Changes

When anti-fraud reminder is disabled: 1. Clears saved scam token hiding setting 2. Updates filter states 3. Refreshes UI

UI Updates

The updateFiltersUI() method: 1. Updates filter indicators in the UI 2. Reflects current filter states to users

Key Methods

readHideLittleAssetsFlag()

  • Purpose: Initialize and update filter states
  • Trigger: Mode changes, app startup
  • Dependencies: Saved settings, current mode status

updateFiltersState()

  • Purpose: Apply filter logic based on mode
  • Parameters:
  • isBasicMode: Basic mode status
  • isAntiCheatOpen: Anti-fraud reminder status
  • savedHideLittleAssets: Saved small assets hiding setting
  • savedHideScamToken: Saved scam token hiding setting

handleBasicModeChanged()

  • Purpose: Handle basic mode state changes
  • Actions:
  • Updates sorting if needed
  • Refreshes filter states

handleAntiCheatChanged()

  • Purpose: Handle anti-fraud reminder state changes
  • Actions:
  • Clears scam token settings if disabled
  • Updates filter states

State Dependencies

  1. Basic Mode Impact:
  2. Overrides small assets hiding setting

  3. Forces user-defined sorting

  4. Anti-Fraud Reminder Impact:

  5. Controls scam token filtering
  6. Clears settings when disabled

UI Integration

The filter states are reflected in the UI through: 1. Filter indicators 2. Asset list display 3. Sorting options

Future Considerations

  1. Potential improvements:
  2. Add more granular filter controls
  3. Implement filter presets

  4. Add filter statistics

  5. Maintenance points:

  6. Monitor filter performance
  7. Track user filter preferences
  8. Optimize filter update frequency
