HelpUIApproach class

UI Approach

Declarative

• what to show from state
  • e.g., in Dart/Flutter:

string = 'Hello World'
build() {
  return Text(string) // text gets destroyed and rebuilt
}

• Updating text on screen can be done by mutating state outside of build
  • e.g., string = string + ! builds HelloWorld!

Imperative

• how to show from state
  • e.g., in Java/Android:

build() {
  return Text.setText('Hello World') // text does not get destroyed, value gets updated
}

• Updating text on screen must be done by accessing current UI state before mutating UI
  • e.g., Text.setText(Text.getText+"!") builds HelloWorld!
