Create a Dedicated Animation Module + +Organize your animation implementations in a dedicated file or module: + +``` +app/ + src/ + main/ + kotlin/ + animations/ + AnimationNodes.kt + AnimationParsers.kt + AnimationTypes.kt +``` + +### 2. Provide Sensible Defaults + +Always provide default values for animation parameters: + +```kotlin +val duration = param.data["duration"]?.toIntOrNull() ?: 300 +val easing = param.data["easing"] ?: "easeInOut" +``` + +### 3. Support Bind Values + +Make sure your animations support bind values for dynamic control: + +```kotlin +val visibleString = param.bindsValue.getValue("isVisible") + ?: param.data["visible"] + ?: "true" +val visible = visibleString.toBoolean() +``` + +### 4. Document Your Custom Animation Nodes + +Create clear documentation for your team on how to use the custom animation nodes in JSON: + +```markdown +## Available Animation Types + +### animated_visibility +- `visible`: "true" or "false" or bind value +- `enterType`: "fadeIn", "slideInVertically", "expandVertically" +- `exitType`: "fadeOut", "slideOutVertically", "shrinkVertically" +- `enterDuration`: milliseconds (default: 300) +- `exitDuration`: milliseconds (default: 300) +``` + +### 5. Test Animations on Different Devices + +Ensure animations perform well across different devices: + +```kotlin +// Consider device capabilities +val duration = if (isLowEndDevice()) 200 else 300 +val enableAnimations = !AccessibilitySettings.areAnimationsDisabled() +``` + +## Troubleshooting + +### Animation Not Triggering + +If your animation isn't triggering: + +1. Check that the bind value is actually changing +2. Verify the visibility string is correctly parsed as boolean +3. Ensure the custom node is registered before rendering + +### Performance Issues + +If animations are choppy: + +1. Reduce animation complexity for low-end devices +2. Use simpler animation types (fade vs slide) +3. Limit the number of simultaneously animating elements + +### Children Not Rendering + +If children aren't appearing: + +1. Ensure you're iterating through `param.children` +2. Pass the correct parameters to `DynamicLayout` +3. Check that the parent container (Column, Box) is properly set up + +## Next Steps + +Now that you've implemented animations: + +1. Create a library of reusable animation patterns +2.

+## Best Practices + +### 1. Keep Animation Durations Consistent + +Use consistent animation durations throughout your app for a cohesive feel: + +- Fast interactions: 150-200ms +- Standard transitions: 250-350ms +- Complex animations: 400-500ms + +### 2. Match Enter and Exit Animations + +For a natural feel, use complementary enter and exit animations: + +```json +{ + "enter": { + "type": "slideInVertically", + "initialOffsetY": "-100" + }, + "exit": { + "type": "slideOutVertically", + "targetOffsetY": "-100" + } +} +``` + +### 3. Use Delays Strategically + +Add small delays to create staggered animations: + +```json +{ + "animated_visibility": { + "visible": "{show}", + "enter": { + "type": "fadeIn", + "durationMillis": 300, + "delayMillis": 100 + } + } +} +``` + +### 4. Consider Performance + +- Avoid animating too many elements simultaneously +- Use simpler animations for complex layouts +- Test animations on lower-end devices + +### 5. Bind to Dynamic Values + +Leverage bind values to control animations from your app: + +```kotlin +val bindsValue = BindsValue() +bindsValue.setValue("isExpanded", "false") +bindsValue.setValue("currentTab", "home") +bindsValue.setValue("showModal", "true") +``` + +## Controlling Animations from Code + +You can control animations by updating bind values: + +```kotlin +// Toggle visibility +val isVisible = remember { mutableStateOf(false) } +val bindsValue = remember { BindsValue() } + +// Update bind value to trigger animation +LaunchedEffect(isVisible.value) { + bindsValue.setValue("menuVisible", isVisible.value.toString()) +} + +DynamicLayout( + component = component, + bindValue = bindsValue +) +``` + +## Animation Easing Functions + +Available easing functions for smooth animations: + +- `linear` - Constant speed throughout +- `easeIn` - Slow start, fast end +- `easeOut` - Fast start, slow end +- `easeInOut` - Slow start and end, fast middle +- `easeInOutCubic` - Smooth cubic curve +- `easeInBack` - Slight overshoot at start +- `easeOutBack` - Slight overshoot at end +- `fastOutSlowIn` - Material Design standard + +## Next Steps + +Now that you understand animations, you can: + +1.
