This widget contains the list of `TextEditingDelta`s, and the callback needed to update the list +when a delta is received from the platform, as well as when the framework reports a delta. Deltas +can be reported by the framework when the selection is changed as a result of a gesture such as tapping or dragging, +when the `TextEditingValue` is updated as a result of a copy/paste, and when the `TextEditingValue` is updated by an `Intent` -> `Action`. + +This widget is primarily used to wrap the `BasicTextField`, so the `BasicTextInputClient`, which is lower in the tree, can +update the history of `TextEditingDelta`s as they are reported by the platform and framework. + +### `TextEditingDeltaView` +A widget that represents the content of a `TextEditingDelta`. A list of `TextEditingDeltaView`s sits below +the input field showcasing a history of `TextEditingDelta`s that have occurred on that input field. A +`TextEditingDeltaView` varies in color depending on the type of `TextEditingDelta`. `TextEditingDeltaInsertion`s +are green, `TextEditingDeltaDeletion`s are red, `TextEditingDeltaReplacement`s are yellow, and `TextEditingDeltaNonTextUpdate`s are blue. + +## Replacements Layer +The layer that handles the styling of the input field, including expanding and contracting the styled ranges based +on the deltas that are received from the platform, and the handling of the state of the styling toggle button toolbar. +This layer contains a mixture of logic unique to this sample and helpful for developers expecting to consume the +`TextEditingDelta` APIs. + +Screen Shot 2022-05-05 at 10 22 27 AM + +### `ToggleButtonsStateManager` +An inherited widget that handles the state of the styling toggle button toolbar that sits on the top +of the input field. This toolbar includes three buttons: Bold, Italic, and Underline. This widget contains +the state of the `ToggleButtons`, and the callbacks needed to update the state when the selection has changed +or when the toggle buttons have been pressed. + +This widget wraps the `ToggleButtons` so it may access the state of the toggle buttons and update that state +when they have been pressed. It also wraps the `BasicTextField`, so that the `BasicTextInputClient`, which is lower +in the tree may access the callback necessary to update the toggle button state when the selection has changed. + +### `TextEditingInlineSpanReplacement` +A data structure that represents a replacement, with a range, and a generator that produces +the desired `InlineSpan`. The generator should return a `TextSpan` with the desired styling, and the +range should be the target range for that styling in the current `TextEditingValue`. This structure also +contains an expand property which dictates if the replacement should continue to expand from the back edge. +For example say we have "Hello |world|", where "world" is covered by a replacement that bolds the text. If +the expand property is true, typing text at the back edge of "world|" will expand the range and make any text +typed also bold. If it is false then the text typed would not be bold. Additionally, this structure contains +methods to update the replacement for each subclass of `TextEditingDelta` and a method to remove a section of +the replacement range. + +### `ReplacementTextEditingController` +A `TextEditingController` that manages a list of `TextEditingInlineSpanReplacement`s, that insert custom `InlineSpan`s +in place of matched `TextRange`s. The controller syncs the replacement ranges based on the type of `TextEditingDelta` +it receives from the `BasicTextInputClient`, managing any overlapping ranges accordingly. + +This controller also contains convenience methods used by the styling toggle buttons toolbar to un-style +certain ranges, disable the expand property of a replacement, and get the common replacements at a selection +to determine the current toggle button state. + +## Text Input Layer +The layer that defines the appearance of a text input field, handles the text input received from +the platform, and mutations done by the framework through gestures and keyboard shortcuts. These classes begin to +demonstrate the types of logic developers may need if they wish to interact with `TextEditingDelta`s. + +Screen Shot 2022-05-05 at 9 57 56 AM + +### `BasicTextField` +A basic text field that defines the appearance, and the selection gestures of a basic text input client. +These gestures call on methods in `RenderEditable` to mutate the `TextEditingValue` through the `TextSelectionDelegate`, +which, in this case, is a the `BasicTextInputClient`. + +This widget wraps the `BasicTextInputClient` to define its appearance such as borders, and selection overlay +appearance based on the platform. + +### `BasicTextInputClient` +A `DeltaTextInputClient`, a `TextInputClient` that receives `TextEditingDelta`s from the platform instead of the +entire `TextEditingValue`. It is responsible for sending/receiving information from the framework to the platforms text input +plugin, and vice-versa. A list of `TextEditingDelta`s is received from the platform and can be handled through +the method `updateEditingValueWithDeltas`. When the framework makes a change to the `TextEditingValue`, the updated value +is sent through the `TextInputConnection.setEditingState` method. + +A `TextSelectionDelegate` that handles the manipulation of selection through toolbar or shortcut keys. + +An `Actions` widget is used to handle certain hardware keyboard shortcuts, such as the backspace key to delete text, and +the left and right arrows keys to move the selection. + +The `RenderObject`, `RenderEditable` (`_Editable`), is used at the leaf node of the `BasicTextInputClient` to render the `TextSpan`s given +by the `ReplacementTextEditingController`. diff --git a/simplistic_editor/analysis_options.yaml b/simplistic_editor/analysis_options.yaml new file mode 100644 index 000000000..5e2133eb6 --- /dev/null +++ b/simplistic_editor/analysis_options.yaml @@ -0,0 +1 @@ +include: ../analysis_options.yaml diff --git a/simplistic_editor/android/.gitignore b/simplistic_editor/android/.gitignore new file mode 100644 index 000000000..6f568019d --- /dev/null +++ b/simplistic_editor/android/.gitignore @@ -0,0 +1,13 @@ +gradle-wrapper.jar +/.gradle +/captures/ +/gradlew +/gradlew.bat +/local.properties +GeneratedPluginRegistrant.java + +# Remember to never publicly share your keystore. +# See https://flutter.dev/docs/deployment/android#reference-the-keystore-from-the-app +key.properties +**/*.keystore +**/*.jks diff --git a/simplistic_editor/android/app/build.gradle b/simplistic_editor/android/app/build.gradle new file mode 100644 index 000000000..4420a33cd --- /dev/null +++ b/simplistic_editor/android/app/build.gradle @@ -0,0 +1,71 @@ +def localProperties = new Properties() +def localPropertiesFile = rootProject.file('local.properties') +if (localPropertiesFile.exists()) { + localPropertiesFile.withReader('UTF-8') { reader -> + localProperties.load(reader) + } +} + +def flutterRoot = localProperties.getProperty('flutter.sdk') +if (flutterRoot == null) { + throw new GradleException("Flutter SDK not found.
