How to force component re-rendering? #211

Hi, same as title, how to force component re rendering?

adospace commented 4 months ago

When you call SetState() you set the state and automatically invalidate the component (that in turn schedules a component re-rendering).

If you want to set the state without re-rendering call SetState(.., invalidateComponent: false) (this is required when you don't want to re-render the component and usually happens when you have property linked to the state using a function like ()=>State.Counter).

If you want to re-render the component just call the Invalidate() (this is required in some special cases).

@adospace Hi, Thank you for your reply! Through step-by-step debugging, I found that it was because the code threw an exception, which resulted in the subsequent SetState not being re-rendered. I am a beginner on Android, and I'm not sure if this meets expectations.
